ARC: mm: fix new code about cache aliasing
Manual/partial revert of 8690bbcf3b70 ("Introduce cpu_dcache_is_aliasing() across all architectures")
Current generation of ARCv2/ARCv3 based HSxx cores are only PIPT (to software
at least).
Legacy ARC700 cpus could be VIPT aliasing (based on cache geometry and
PAGE_SIZE) [1] however recently that support was ripped out so VIPT aliasing
cache is not relevant to ARC anymore.
