media: mpeg2-ctrls.h: move MPEG2 state controls to non-public header The MPEG2 state controls for the cedrus stateless MPEG2 driver are not yet stable. Move them out of the public headers into media/mpeg2-ctrls.h. Eventually, once this has stabilized, they will be moved back to the public headers. Unfortunately I had to cast the control type to a u32 in two switch statements to prevent a compiler warning about a control type define not being part of the enum.

media: cedrus: identify buffers by timestamp 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.
