media: v4l2-subdev: convert frame description to enum
As kernel-doc doesn't support documenting #define values, and using enum makes easier to identify where the values are used, convert V4L2_MBUS_FRAME_DESC_FL_* to enum, and use BIT() macro. While here, fix the description at v4l2_mbus_frame_desc_entry, in order to match what's described for V4L2_MBUS_FRAME_DESC_FL_LEN_MAX. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
