drm/i915/psr: set PSR_MASK bits for deep sleep
Program EDP_PSR_DEBUG_CTL (PSR_MASK) to enable system
to go to deep sleep while in psr2.PSR2_STATUS bit 31:28
should report value 8 , if system enters deep sleep state.
Also, EDP_FRAMES_BEFORE_SU_ENTRY is set 1 , if not set,
flickering is observed on psr2 panel.
