V4L/DVB (12149): videodev2.h: Reorganize fourcc table
With the changes this file suffered along the time, things got a little disorganized. In particular, V4L2_PIX_FMT_YVYU were shown as a device-specific format, instead of yet another variant of YUV. There's no functional change on this patch. It just adds some comments and reorder fourcc formats to their proper places. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
