drm/i915/fbc: Remove stale FIXME

Remove the old tales about 90/270 degree rotation
effectively preventing FBC. That hasn't been true since
we stopped demanding the fence is present in
commit 691f7ba58d ("drm/i915/display/fbc: Make fences
a nice-to-have for GEN9+")

Also fix up the multiline comment formatting while at it.
