drm/radeon: program auxch directly (v2)
The atombios tables have an unfortunate restriction on only
being able to write 12 bytes, MST really wants 16-bytes here,
and since the hw can do it, we should just write directly to it.
This uses a module option to allow for it now, and maybe
we should provide the old code as a fallback for a while.
v2: (agd5f)
- move registers to a proper register header
- only enable on DCE5+
- enable by default on DCE5+
- Switch pad to aux mode before using it
- reformat instance handling to better match the
rest of the driver
