We currently don't support dirty rectangles on hardware rotated modes.
So, if a user is using hardware rotated modes with PSR-SU enabled,
use PSR-SU FFU for all rotated planes (including cursor planes).

Looks like a spurious newline here.

I noticed that the original report was specifically on 180°. Since
you're also covering 90° and 270° with this check it sounds like it's
actually problematic on those too?

As a nit; I think it's worth leaving a harmless trailing ',' so that
there is less ping pong in the future when adding new members to a struct.
