    xen/arm: Add arm64 ID registers definitions
    
    Add coprocessor registers definitions for all ID registers trapped
    through the TID3 bit of HSR.
    Those are the one that will be emulated in Xen to only publish to guests
    the features that are supported by Xen and that are accessible to
    guests.
