We might be leaving the GPU Frequency (and thus vnn) high during the suspend.
Force gt to move to lowest freq while suspending.
v2: Fixed typo in commit message (Deepak)
v3: Force gt to lowest freq in suspend_gt_powersave (Daniel)
v4: Add GPU min freq set _after_ we've cancelled the rps works (Daniel)
