arm64: mm: cleanup stale AIVIVT references
Since commit: 155433cb365ee466 ("arm64: cache: Remove support for ASID-tagged VIVT I-caches") ... the kernel no longer cares about AIVIVT I-caches, as these were removed from the architecture. This patch removes the stale references to such I-caches. The comment in flush_context() is also updated to clarify when and where the TLB invalidation occurs.
