Imre Deak 9486db611c drm/i915: reinit GT power save during resume
During runtime suspend there can be a last pending rps.work, so make
sure it's canceled. Note that in the runtime suspend callback we can't
get any RPS interrupts since it's called only after the GPU goes idle
and we set the minimum RPS frequency. The next possibility for an RPS
interrupt is only after getting an RPM ref (for example because of a new
GPU command) and calling the RPM resume callback.

v2:
- patch introduced in v2 of the patchset
v3:
- Change the order of canceling the rps.work and disabling interrupts to
  avoid the race between interrupt disabling and the the rps.work. Race
  spotted by Ville.
