[media] pxa_camera: merge soc_mediabus.c into pxa_camera.c

Linking soc_mediabus into this driver causes multiple definition linker warnings
if soc_camera is also enabled:

   (.text+0x3840): multiple definition of `soc_mbus_config_compatible'
   drivers/media/platform/soc_camera/soc_mediabus.o:(.text+0x134): first defined here

Since we really don't want to have to use any of the soc-camera code this patch
copies the relevant code and data structures from soc_mediabus and renames it to pxa_mbus_*.

The large table of formats has been culled a bit, removing formats that are not supported
by this driver.
