    xlat: Set AP[1] to 1 when it is RES1 · 01c0a38e

    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.
