drm/i915/psr: Add mechanism to notify PSR of pipe enable/disable

Browse source

We need to apply/remove workaround for underrun on idle PSR HW issue
(Wa_16025596647) when new pipe is enabled or pipe is getting disabled. This
patch implements mechanism to notify PSR about pipe enable/disable and
applies/removes the workaround using this notification.
