drm/radeon: fix halting UVD
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. Signed-off-by: Christian König <christian.koenig@amd.com> Cc: stable@vger.kernel.org Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
