drm/i915: make runtime PM interrupt enable/disable platform independent
We need to disable the interrupts for all platforms, so make the helpers
for this platform independent and call them from them platform
independent runtime suspend/resume callbacks.
On HSW/BDW this will move interrupt disabling/re-enabling at the
beginning/end of runtime suspend/resume respectively, but I don't see
any reason why this would cause a problem there. In any case this seems
to be the correct thing to do even on those platforms.
