arc: remove read ahead in asm strcmp code for ARCHS
Remove read ahead in the per-word compare loop as it can cause a
segmentation fault in certain circumstances (when a string crosses a
page boundary). For baremetal this relaxed approach is suitable but
in Linux with MMU we should be more restrictive.
