parisc: Fix invalidate/flush vmap routines
Cache move-in for virtual accesses is controlled by the TLB. Thus,
we must generally purge TLB entries before flushing. The flush routines
must use TLB entries that inhibit cache move-in.
V2: Load physical address prior to flushing TLB. In flush_cache_page,
flush TLB when flushing and purging.
V3: Don't flush when start equals end.
