drm/i915: Unifiy GT powersave suspend logic
Jesse's patch to only quiescent our rps work and Imre's fix to address
a race with runtime pm and the forcewake reference held by the used
diverging means to address the same bug: Jesse's patch uses
flush_delayed_work while (since we want to make sure rps is set up)
while Imre's used a cancel+manuel refcount adjustment.
Unify them again by simply reusing intel_suspend_gt_powersave in
intel_disable_gt_powersave.
