[media] V4L: Add capability flags for memory-to-memory devices
This patch adds new V4L2_CAP_VIDEO_M2M and V4L2_CAP_VIDEO_M2M_MPLANE capability flags that are intended to be used for memory-to-memory (M2M) devices, instead of ORed V4L2_CAP_VIDEO_CAPTURE and V4L2_CAP_VIDEO_OUTPUT. V4L2_CAP_VIDEO_M2M flag is added at the drivers, CAPTURE and OUTPUT capability flags are left untouched and will be removed in future, after a transition period required for existing applications to be adapted to check only for V4L2_CAP_VIDEO_M2M.
