media: cedrus: identify buffers by timestamp

Browse source 
Use the new v4l2_m2m_buf_copy_data helper function and use
timestamps to refer to reference frames instead of using
buffer indices.

Also remove the padding fields in the structs, that's a bad
idea. Just use the right types to keep everything aligned.
