drm/i915/psr: Repeat Selective Update area alignment

Browse source

commit 1be2fca84f upstream.

Currently we are aligning Selective Update area to cover cursor fully if
needed only once. It may happen that cursor is in Selective Update area
after pipe alignment and after that covering cursor plane only
partially. Fix this by looping alignment as long as alignment isn't needed
anymore.

v2:
  - do not unecessarily loop if cursor was already fully covered
  - rename aligned as su_area_changed
