[PATCH 1/2] drm/amdgpu: fix s3 resume back, uvd dpm randomly can't disable.

[Rex Zhu]

the value of last_mclk_dpm_enable_mask will be changed if
other clients(vce,dal) trigger set power state between enable
and disable uvd dpm.

I think this hunk should be a separate patch.  Also, should we
actually return here or just print a message?

Ideally we would save the selected state before forcing it to boot
mode in suspend and then restore the user state in resume.
