[media] media: videobuf2: Replace v4l2-specific data with vb2 data
Simple changes that replace v4l2-specific data with vb2 data
in videobuf2-core.
enum v4l2_buf_type --> int
enum v4l2_memory --> enum vb2_memory
VIDEO_MAX_FRAME --> VB2_MAX_FRAME
VIDEO_MAX_PLANES --> VB2_MAX_PLANES
struct v4l2_fh *owner --> void *owner
V4L2_TYPE_IS_MULTIPLANAR() --> is_multiplanar
V4L2_TYPE_IS_OUTPUT() --> is_output
