It is a preliminary work for supporting multiple EDP PSR and
DP PanelReplay. And it refactors singleton PSR to Multi Transcoder
supportable PSR.
And this moves and renames the i915_psr structure of drm_i915_private's to
intel_dp's intel_psr structure.
It also causes changes in PSR interrupt handling routine for supporting
multiple transcoders. But it does not change the scenario and timing of
enabling and disabling PSR.
v2: Fix indentation and add comments
v3: Remove Blank line
v4: Rebased
v5: Rebased and Addressed Anshuman's review comment.
- Move calling of intel_psr_init() to intel_dp_init_connector()
