drm/i915: add update function to disable/enable-back PSR
Required function to disable PSR when going to console mode.
But also can be used whenever PSR mode entry conditions changed.
v2: Add it before PSR Hook. Update function not really been called yet.
v3: Fix coding style detected by checkpatch by Paulo Zanoni.
v4: do_enable must be static as Paulo noticed.
