Embed video_device struct (video_dev) in vpfe_device and
Unregister path doesn't need to free the video_device
structure, hence, change the video_device.release callback
point to video_device_release_empty.

Instead of matching the subdevs with their name, match
it with OF node/ i2c address and adapter number.

The remote port reference is released both at the end of the OF graph
parsing loop, and in the error code path at the end of the function.
Those two calls will release the same reference, causing the reference
count to go negative.
Fix the problem by removing the second call.

Support the new 'which' field in the enum_frame_size ops. Most drivers do not
need to be changed since they always returns the same enumeration regardless
of the 'which' field.

VIDEO_AM437X_VPFE selects VIDEOBUF2_DMA_CONTIG, which bypasses its
dependency on HAS_DMA. Make VIDEO_AM437X_VPFE depend on HAS_DMA to fix
this.
