Message

Hello,

Suggested by Hans at [1], this patchset is promoting a standard control
for frame skip mode.

The original private V4L2_CID_MPEG_MFC51_VIDEO_FRAME_SKIP_MODE control is
applicable and can be used by Venus driver too (and probably other drivers).
In order to make that possible make a new V4L2_CID_MPEG_VIDEO_FRAME_SKIP_MODE
standard menu control (a copy of the private one).

Also, to keep mfc driver backward compatible kept the private one, and mark
it as depricated in docs.

regards,
Stan
