Subject: V4L/DVB (9361): Dynamic DVB minor allocation

Implement dynamic minor allocation for DVB, to allow more than four
devices of the same type per adapter, based on drivers/usb/core/file.c.

Add a new config option, DVB_DYNAMIC_MINORS, to make use of this
feature, which defaults to no for backwards compatibility.

+	  allocation for any device that uses the DVB major number.
+	  This means that you can have more than 4 of a single type
+	  of device (like demuxes and frontends) per adapter, but udev
+	  will be required to manage the device nodes.

Subject: V4L/DVB (9364): adding sharp s921 ISDB-T driver

s921_module.c:
    wrapper for the dvb frontend interface
    s921_core.c:
    core s921 1seg ISDB-T driver, everything is set to auto as much as possible
    in order to not require certain parameters which currently cannot be passed
    to the ISDB-T chip.

    ISDB-T support can be tested using dvbscan, dvbstream/snoop and mplayer
    Tested 1seg H264/aac stream with this driver using a custom linux
ISDB-T player
