Subject: [v3 0/5] Add PSR support for eDP

Changes in v2:
  - Use dp bridge to set psr entry/exit instead of dpu_enocder.
  - Don't modify whitespaces.
  - Set self refresh aware from atomic_check.
  - Set self refresh aware only if psr is supported.
  - Provide a stub for msm_dp_display_set_psr.
  - Move dp functions to bridge code.

Changes in v3:
  - Change callback names to reflect atomic interfaces.
  - Move bridge callback change to separate patch as suggested by Dmitry.
  - Remove psr function declaration from msm_drv.h.
  - Set self_refresh_aware flag only if psr is supported.
  - Modify the variable names to simpler form.
  - Define bit fields for PSR settings.
  - Add comments explaining the steps to enter/exit psr.
  - Change DRM_INFO to drm_dbg_db.
