V4L/DVB (12761): DocBook: add media API specs
The V4L and DVB API's are there for a long time. however, up to now, no efforts were done to merge them to kernel DocBook. This patch adds the current versions of the specs as an unique compendium. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

670 Although std_id is 64 bits, there is an issue on PPC32 architecture that
671 makes switch(__u64) to break. So, there's a hack on v4l2-common.c rounding
672 this value to 32 bits.
673 As, currently, the max value is for V4L2_STD_ATSC_16_VSB (30 bits wide),
674 it should work fine. However, if needed to add more than two standards,
675 v4l2-common.c should be fixed.
