drm/amd/display: Issue with 3 or more mcaches per surface
[Why & How]
Current logic in mcache admissibility check has flaw if
calculated number of maches are 3 or more per surface,
so sometimes the check may pass when it should fail,
and sometimes may fail when it should pass, fix the
issue and also adding additional check to make sure that
required number of mcaches per surface cannot be
higher than number of pipes + 1, used on that surface.
