drm/i915/mtl: Introduce FBC B
MTL introduces a second FBC engine. The two FBC engines can
operate entirely independently, FBC A serving pipe A and
FBC B serving pipe B.
The one place where things might go a bit wrong is the CFB
allocation from stolen. We might have to consider some change
to the allocation strategy to have a better chance of both
engines being able to allocate its CFB. Maybe FBC A should
allocate bottom up and FBC B top down, or something? For the
moment the allocation strategy is DRM_MM_INSERT_BEST for both.
