arm64: allow ioremap_cache() to use existing RAM mappings Some drivers (ACPI notably) use ioremap_cache() to map an area which could either be outside of kernel RAM or in an already mapped reserved area of RAM. To avoid aliases with different caching attributes, ioremap() does not allow RAM to be remapped. But for ioremap_cache(), the existing kernel mapping may be used.
