NVIDIA: SAUCE: include/linux: Add new packed v4l2 pixel format

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2072591

Add pacekd 10-bit formats to v4l2 pixel formats list.
X(Bayer)10 packs 3 pixels to 4 bytes with two MSB bits
set to zero. All four corresponding phases are added.

Snapshot of packing different bayer formats below:
BGGR10 - X2B10G10B10 X2G10B10G10.. X2G10R10G10 X2R10G10R10..
RGGB10 - X2R10G10R10 X2G10R10G10.. X2G10B10G10 X2B10G10B10..
GRGB10 - X2G10R10G10 X2R10G10R10.. X2G10B10G10 X2B10G10B10..
GBGR10 - X2G10B10G10 X2B10G10B10.. X2G10R10G10 X2R10G10R10..

In general if the pixels are L0L1L2L3L4L5.., the packed
32-bit integers would be X2L2L1L0 X2L5L4L3..

Add corresponding MBUS formats to represent packed 10bit.
