Message

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.
