CVS commit: src/sys/arch/aarch64/aarch64

Module Name:    src

Modified Files:
        src/sys/arch/aarch64/aarch64: locore.S

Log Message:
Adjust register usage a bit and unbreak DEBUG_MMU as a result.

The change moves to using callee-saved registers more so that any call
into C will have them preserved (if they're used or not).  It's safe
to use stack as it's setup very early for BP/APs.
