Align usage of get_reg/set_reg functions with actual content of
struct pt_regs and struct callee_regs for ARCv2/ARCv3
Since major opcodes for ARCv2/ARCv2/ARCv3 are slightly different
between ISAs, then we need to recognize instructions sizes differently
depending on the architecture.
We need to flush instruction $ not only from vmalloc area but also
from another memory ranges when using kprobe as exemple.
Correct this.

Squash this patch with "ARCv3: Add support L2$ flush/invalidate
operations", f11124f
