more scheduled OSS driver removal

This patch contains the scheduled removal of OSS drivers that:
- have ALSA drivers for the same hardware without known regressions and
- whose Kconfig options have been removed in 2.6.20.

- *	Changes:
- *	20000909-nf	Changed cs_read, cs_write and drain_dac
- *	20001025-tw	Separate Playback/Capture structs and buffers.
- *			Added Scatter/Gather support for Playback.
- *			Added Capture.
- *	20001027-nf	Port to kernel 2.4.0-test9, some clean-ups
- *			Start of powermanagement support (CS46XX_PM).
- *	20001128-tw	Add module parm for default buffer order.
- *			added DMA_GFP flag to kmalloc dma buffer allocs.
- *			backfill silence to eliminate stuttering on
- *			underruns.
- *	20001201-tw	add resyncing of swptr on underruns.
- *	20001205-tw-nf	fixed GETOSPACE ioctl() after open()
- *	20010113-tw	patch from Hans Grobler general cleanup.
- *	20010117-tw	2.4.0 pci cleanup, wrapper code for 2.2.16-2.4.0
- *	20010118-tw	basic PM support for 2.2.16+ and 2.4.0/2.4.2.
- *	20010228-dh	patch from David Huggins - cs_update_ptr recursion.
- *	20010409-tw	add hercules game theatre XP amp code.
- *	20010420-tw	cleanup powerdown/up code.
- *	20010521-tw	eliminate pops, and fixes for powerdown.
- *	20010525-tw	added fixes for thinkpads with powerdown logic.
- *	20010723-sh     patch from Horms (Simon Horman) -
- *	                SOUND_PCM_READ_BITS returns bits as set in driver
- *	                rather than a logical or of the possible values.
- *	                Various ioctls handle the case where the device
- *	                is open for reading or writing but not both better.
- *
- *	Status:
- *	Playback/Capture supported from 8k-48k.
- *	16Bit Signed LE & 8Bit Unsigned, with Mono or Stereo supported.
- *
- *	APM/PM - 2.2.x APM is enabled and functioning fine. APM can also
- *	be enabled for 2.4.x by modifying the CS46XX_ACPI_SUPPORT macro
- *	definition.
- *
- *      Hercules Game Theatre XP - the EGPIO2 pin controls the external Amp,
- *	so, use the drain/polarity to enable.  
- *	hercules_egpio_disable set to 1, will force a 0 to EGPIODR.
- *
- *	VTB Santa Cruz - the GPIO7/GPIO8 on the Secondary Codec control
- *	the external amplifier for the "back" speakers, since we do not
- *	support the secondary codec then this external amp is also not
- *	turned on.
