drm/radeon: fixes for gfx clockgating on CIK
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.
