Fill in asic family specific versions rather than

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.

Now that the CP is no longer reset and cg is properly

now enable mgcg (medium grained clockgating).
Signed-off-by: NAlex Deucher <alexander.deucher@amd.com>

Clockgating requires signalling between the CP and the
RLC to work properly.  Resetting the CP block in the
CP resume code messed up the internal coordination
between the blocks.  Removing the reset allows gfx
clockgating to work properly.  However, when gfx clock
gating is enabled, there is a strange interaction with
dpm which causes the chip to stay in the high performance
level all the time, so leave gfx clockgating disabled
for now.
