Dirty rect support for FBC in xe3 onwards based on the comments after the
initial RFC series.

v2: Dirty rect related compute and storage moved to fbc state (Ville)

V3: Dont call fbc activate if FBC is already active

v4: Dirty rect compute and programming moved within DSB scope
    New changes are added as separate patches to make it easy for review
    But could be squashed if the reviews as ok.

v5: add HAS_FBC_DIRTY_RECT()
    FBC Damage area updates in 3 steps. 
    1. As part of plane_atomic_check() get, adjust coordinates and store
       the merged damage area in plane_state
    2. Atomic_commit, update merged damage are to fbc_state and prepare the
       damage area satifying all conditions
    3  update the FBC dirty rect registers as part of DSB commit.

v6: Use dmage_merged helper earlier to handle bigjoiner cases (Ville)
    Place the damage_merged handling code under HAS_FBC_DIRTY_RECT()
    Added a variable to check if the damage_merged received from
    the helper is valid. And if it is not valid, the FBC dirty rect
    is updated with full plane reqion.

v7: Reordering of the patches
    Updates to storage of damage to plane state as per comments from Ville
    Updates to dirty rect handling in FBC as per comments from Ville

v8: Patch subject and description updates
    Address to comments from Ville

Vinod Govindapillai (7):
  drm/damage-helper: add const qualifier in
    drm_atomic_helper_damage_merged()
  drm/i915/display: update and store the plane damage clips
  drm/i915/fbc: add register definitions for fbc dirty rect support
  drm/i915/fbc: introduce HAS_FBC_DIRTY_RECT() for FBC dirty rect
    support
  drm/i915/fbc: avoid calling fbc activate if fbc is active
  drm/i915/fbc: dirty rect support for FBC
