Fix the read/write flag for these registers on AArch64

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.
