xlat lib: Remove out-dated comment

As of commit e1ea9290bb, if the attributes of an inner memory region
are different than the outer region, new page tables are generated
regardless of how "restrictive" they are. This patch removes an
out-dated comment still referring to the old priority system based
on which attributes were more restrictive.
