    xlat v2: Dynamically detect need for CnP bit · 2559b2c8

    ARMv8.2-TTCNP is mandatory from ARMv8.2 onwards, but it can be implemented
    in CPUs that don't implement all mandatory 8.2 features (and so have to
    claim to be a lower version).
    
    This patch removes usage of the ARM_ARCH_AT_LEAST() macro and uses system
    ID registers to detect whether it is needed to set the bit or not.
