ARC: Use correct PTAG register for icache flush

This fixes a subtle issue with cache flush which could potentially cause
random userspace crashes because of stale icache lines.

This error crept in when consolidating the cache flush code

Fixes: bd12976c3664 (ARC: cacheflush refactor #3: Unify the {d,i}cache)
