rG73c200447361: arm64: Use the pointer auth register defines

Summary

When building with gcc it complains the pointer authentication
registers aren't valid with the architecture level we are targeting.
Fix this by using the alternative spelling of these registers accesses
through MRS_REG_ALT_NAME.
