drm/i915/psr: Change psr size limits check

Change the check to only check for psr size limits till Pre-Xe2
since after that the psr size is equal to maximum pipe size anyways.

--v2
-Check only size limit until pre-Xe2 [Matt]

--v3
-Make sure psr_max_{h,v} and max_bpp are equal to crtc_{h,v}_display
and pipe_bpp [Ankit]
