[Intel-gfx] [PATCH v3 2/4] drm/i915/psr: Prevent PSR exit when a non-pipe related register is written

Any write in any display register was causing HW to exit PSR, masking it to allow more power savings. Writes to pipe related registers will still cause HW to exit PSR. This is already masked for PSR2. Bspec: 7721 and 8042 Cc: Rodrigo Vivi Cc: Dhinakaran Pandiyan
