Certain r6xx boards use the same power state for both UVD
and other things.  Since we don't support UVD on r6xx boards
at the moment, there was no callback installed for setting
the UVD clocks, however, on systems that use the same power
state, this leads to a NULL pointer dereference.  Fill
in a stubbed out implementation for now to avoid the crash.

Allows you to limit the selected power levels via sysfs.

Force the feedback divider to select a power level.

v2: fix checking in rs780_force_fbdiv,
    drop a duplicate divider structure in rs780_dpm_force_performance_level,
    Force the voltage level too.

Similar to DCE4/5, but supports multiple audio pins
which can be assigned per afmt block.

v2: rework the driver to handle more than one audio
pin.
v3: try different dto reg
v4: properly program dto
v5 (ck): change dto programming order
v6: program speaker allocation block
v7: rebase
v8: rebase on Rafał's changes
v9: integrated Rafał's comments, update to latest
    drm_edid_to_speaker_allocation API
v10: add missing line break in error message
v11: add back audio enabled messages

Our different hardware blocks are actually completely
separated, so it doesn't make much sense any more to

Start restructuring the code by separating our the UVD block.

Disable the UVD block when not in use to save power.
The block is not actually powergated on CI, but we
switch between UVD DPM (where the uvd clocks are
adjusted on demand) and clocks off.

Due to the way the hardware works on these asics, there's

we make the best guess we can based on the current sclk.
