drm/i915: Extract i915gm_irq_cstate_wa_{disable,enable}()

Browse source

Extract the i915gm/i945gm vblank irq C-state workaround to
separate functions. We'll need to reuse these in order to
guarantee timely CRC interrupt delivery as well.

The irq.vblank_enabled count is currently protected by the
drm vblank locks, so let's assert that the innermost of those
is held, in anticipation of other callers.
