drm/radeon: fix halting UVD
commit 2858c00d2823c83acce2a1175dbabb2cebee8678 upstream.
Removing the clock/power or resetting the VCPU can cause
hangs if that happens in the middle of a register write.
Stall the memory and register bus before putting the VCPU
into reset. Keep it in reset when unloading the module or
suspending.
v2: rebased on 3.10-stable tree
