xlat: Set AP[1] to 1 when it is RES1
According to the ARMv8 ARM issue C.a:
AP[1] is valid only for stage 1 of a translation regime that can
support two VA ranges. It is RES 1 when stage 1 translations can
support only one VA range.
This means that, even though this bit is ignored, it should be set to 1
in the EL3 and EL2 translation regimes.
For translation regimes consisting on EL0 and a higher regime this bit
selects between control at EL0 or at the higher Exception level. The
regimes that support two VA ranges are EL1&0 and EL2&0 (the later one
is only available since ARMv8.1).
This fix has to be applied to both versions of the translation tables
library.
