[Intel-gfx] [PATCH 02/20] drm/i915/fbc: Pass whole plane state to intel_fbc_min_limit()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

No reason to burden the caller with the details on how the minimum
compression limit is calculated, so just pass in the whole plane
state instead of just the cpp value.
