arm: Fix PMSA regions for contiguous sections

Browse Source 
Sections with identical attributes may be contiguous with a respective
begin and end address which is not on a minimum region boundary.  The
begin address is aligned down to the region base address.  The end
address is aligned up to the region end address.  Account for this in
the check for contiguous sections.

Update #4202.
