commit 4a57f3ebb21db6b89b0ceb9df34d32157731ead2
Author: Antonio Borneo <bor...@gm...>
Date:   Thu May 25 10:49:20 2023 +0200

    target: armv8: fix support of pointer authentication
    
    The registers pauth_dmask and pauth_cmask are not accessible in
    AARCH32 mode. Tagging them as 'hidden' is not enough and triggers
    error:
            Failed to read pauth_dmask register
    while halting the core.
    
    Tag the pauth registers as not existing, unless required by user.
    
    Note: for non existing registers there should be no need to
          allocate their register cache. Let's keep this for a further
          improvement.
