feat(rme): add xlat table library changes for FEAT_RME
FEAT_RME adds a new bit (NSE) in the translation table descriptor
to determine the Physical Address Space (PAS) of an EL3 stage 1
translation according to the following mapping:
TTD.NSE TTD.NS | PAS
=================================
0 0 | Secure
0 1 | Non-secure
1 0 | Root
1 1 | Realm
This patch adds modifications to version 2 of the translation table
library accordingly. Bits 4 and 5 in mmap attribute are used to
determine the PAS.
