[PATCH v2 10/11] drm/i915: Improve PSR2 CTL macros

[José Roberto de Souza]

- Reusing the EDP_PSR2_FRAME_BEFORE_SU_SHIFT in EDP_PSR2_FRAME_BEFORE_SU
- Removing unused EDP_PSR2_FRAME_BEFORE_SU_MASK
- Adding EDP_PSR2_FRAME_BEFORE_SU_MAX
- Adding EDP_PSR2_IDLE_FRAME()
- Adding EDP_PSR2_IDLE_FRAME_MAX

In the next patch the new macros will be used.
