Fix the read/write flag for these registers on AArch64
    
    The previous constraints were based on information already in opcodes and it
    seems that a few of them were wrong.  I have now hand verified the ones changed
    by the previous patch and corrected where needed.
    
    This prevents a warning to be issued when one shouldn't be.
