Staging: dt3155: remove the driver

There is now a proper V4L driver for this device in the tree,
so remove this one.

-
-The allocator shown here  exploits high memory. This document explains
-how  a user can  deal   with drivers uses   this  allocator and how  a
-programmer can link in the module.
-
-The module is being used by my pxc and pxdrv device drivers (as well as
-other ones), available from ftp.systemy.it/pub/develop and
-ftp.linux.it/pub/People/Rubini
-
-	User's manual
-	=============
-
-
-One of the most compelling problems with any DMA-capable device is the
-allocation  of a suitable  memory buffer. The "allocator" module tries
-to deal with  the problem in  a clean way.  The module is  able to use
-high   memory  (above the  one   used in  normal   operation)  for DMA
-allocation.
-
-To prevent  the  kernel for using   high memory,  so  that it  remains
-available for  DMA, you should  pass a  command  line argument to  the
-kernel.  Command line arguments  can be passed to  Lilo, to Loadlin or
-to whichever loader  you are using  (unless it's very poor in design).
-For Lilo, either use  "append=" in  /etc/lilo.conf or add  commandline
-arguments to the  interactive prompt. For  example, I have a 32MB  box
-and reserve two megs for DMA:
-
-In lilo.conf:
-	image = /zImage
-	label = linux
-	append = "mem=30M"
-
-Or, interactively:
-	LILO: linux mem=30M
-
-Once  the kernel is booted  with the  right command-line argument, any
-driver  linked   with  the  allocator   module  will  be able   to get
-DMA-capable memory without  much  trouble (unless the  various drivers
-need more memory than available).
-
-The module implements an alloc/free  mechanism,  so that it can  serve
-multiple drivers  at the  same time. Note  however that  the allocator
-uses all of  high memory and assumes to  be the only piece of software
-using such memory.
-
-
-	Programmer's manual
-	===================
-
-The allocator,  as  released, is designed  to  be linked  to  a device
-driver.  In this  case, the driver  must call allocator_init()  before
-using   the  allocator   and  must  call   allocator_cleanup()  before
-unloading.  This is  usually  done   from within  init_module()    and
-cleanup_module(). If the allocator is linked to  a driver, it won't be
-possible for several drivers to allocate high DMA memory, as explained
-above.
-
-It is possible, on the other hand, to compile the module as a standalone
-module, so that several modules can rely on the allocator for they DMA
-buffers. To compile the allocator as a standalone module, do the
-following in this directory (or provide a suitable Makefile, or edit
-the source code):
-
-	make allocator.o CC="gcc -Dallocator_init=init_module -Dallocator_cleanup=cleanup_module -include /usr/include/linux/module.h"
-
-The previous commandline  tells   to include <linux/module.h>  in  the
-first place,  and to rename the init  and cleanup function to the ones
-needed for  module loading and  unloading.  Drivers using a standalone
-allocator won't need to call allocator_init() nor allocator_cleanup().
-
-The allocator exports the following functions (declared in allocator.h):
-
-   unsigned long allocator_allocate_dma (unsigned long kilobytes,
-					 int priority);
-
-	This function returns a physical address, over high_memory,
-	which corresponds to an area of at least "kilobytes" kilobytes.
-	The area will be owned by the module calling the function.
-	The returned address can be passed to device boards, to instruct
-	their DMA controllers, via phys_to_bus(). The address can be used
-	by C code after vremap()/ioremap(). The "priority" argument should
-	be GFP_KERNEL or GFP_ATOMIC, according to the context of the
-	caller; it is used to call kmalloc(), as the allocator must keep
-	track of any region it gives away. In case of error the function
-	returns 0, and the caller is expected to issue a -ENOMEM error.
-
-
-   void allocator_free_dma (unsigned long address);
-
-	This function is the reverse of the previous one. If a driver
-	doesn't free the DMA memory it allocated, the allocator will
-	consider such memory as busy. Note, however, that
-	allocator_cleanup() calls kfree() on every region it reclaimed,
-	so that a driver with the allocator linked in can avoid calling
-	allocator_free_dma() at unload time.

-  -------------------------------------------------------------------
-  02-Aug-2002 NJC         allocator now steps in 1MB increments, rather
-			  than doubling its size each time.
-			  Also, allocator_init(u32 *) now returns
-			  (in the first arg) the size of the free
-			  space.  This is no longer consistent with
-			  using the allocator as a module, and some changes
-			  may be necessary for that purpose.  This was
-			  designed to work with the DT3155 driver, in
-			  stand alone mode only!!!
-  26-Oct-2009 SS	  Port to 2.6.30 kernel.

--- Changes --
-
-  Date     Programmer	Description of changes made
-  -------------------------------------------------------------------
-  03-Jul-2000 JML       n/a
-  10-Oct-2001 SS        port to 2.4 kernel
-  02-Apr-2002 SS        Mods to use allocator as a standalone module;
-                        Merged John Roll's changes (john@cfa.harvard.edu)
-                        to make work with multiple boards.
-  02-Jul-2002 SS        Merged James Rose's chages (rosejr@purdue.edu) to:
-                         * fix successive interrupt-driven captures
-                         * add select/poll support.
-  10-Jul-2002 GCS       Add error check when ndevices > MAXBOARDS.
-  02-Aug-2002 GCS       Fix field mode so that odd (lower) field is stored
-                        in lower half of buffer.
-  05-Aug-2005 SS        port to 2.6 kernel.
-  26-Oct-2009 SS	port to 2.6.30 kernel.
-
--- Notes --
-
-** appended "mem=124" in lilo.conf to allow for 4megs free on my 128meg system.
- * using allocator.c and allocator.h from o'reilly book (alessandro rubini)
-    ftp://ftp.systemy.it/pub/develop (see README.allocator)
-
- + might want to get rid of MAXboards for allocating initial buffer.
-    confusing and not necessary
-
- + in dt3155_exit the MOD_IN_USE looks like it is check after it should
-
- * GFP_DMA should not be set with a PCI system (pg 291)
-
- - NJC why are only two buffers allowed? (see isr, approx line 358)
