xen: mapcache: Unmap first entries in buckets
When invalidating memory ranges, if we happen to hit the first
entry in a bucket we were never unmapping it. This was harmless
for foreign mappings but now that we're looking to reuse the
mapcache for transient grant mappings, we must unmap entries
when invalidated.

xen: mapcache: Pass the ram_addr offset to xen_map_cache()
Pass the ram_addr offset to xen_map_cache.
This is in preparation for adding grant mappings that need
to compute the address within the RAMBlock.
No functional changes.

Log Message:
-----------
xen: mapcache: Add support for grant mappings
Add a second mapcache for grant mappings. The mapcache for
grants needs to work with XC_PAGE_SIZE granularity since
we can't map larger ranges than what has been granted to us.
Like with foreign mappings (xen_memory), machines using grants
are expected to initialize the xen_grants MR and map it
into their address-map accordingly.
