media: v4l2-ctrl: Change control for VP8 profile to menu control
Add a menu control V4L2_CID_MPEG_VIDEO_VP8_PROFILE for VP8 profile and make V4L2_CID_MPEG_VIDEO_VPX_PROFILE an alias of it. This new control is used to select the desired profile for VP8 encoder and query for supported profiles by VP8 encoder/decoder. Though we have originally a control V4L2_CID_MPEG_VIDEO_VPX_PROFILE and its name contains 'VPX', it works only for VP8 because supported profiles usually differ between VP8 and VP9. In addition, this control cannot be used for querying since it is not a menu control but an integer control, which cannot return an arbitrary set of supported profiles. The new control V4L2_CID_MPEG_VIDEO_VP8_PROFILE is a menu control as with controls for other codec profiles. (e.g. H264) In addition, this patch also fixes the use of V4L2_CID_MPEG_VIDEO_VPX_PROFILE in drivers of Qualcomm's venus and Samsung's s5p-mfc.
