drm/i915/display: Remove FBC modulo 4 restriction for ADL-P+
WA:22010751166 does not apply past display version 12. Or, in
other words, the FBC restriction where FBC is disabled for
non-modulo 4 plane sizes (including plane size + yoffset) is fixed
from display version 13 and onwards. Relax the restriction for the same.
v4: Dropped redundant commit message
v3: Update comments for clarity (Jonathan Cavitt)
v2: Update the macro for display version check (Vinod)
