Subject: [PATCH v3 17/24] sfi: switch from ioremap_cache to memremap

In preparation for deprecating ioremap_cache() convert its usage in sfi
to memremap.  It's a bit awkward that we go and add back a fake __iomem
annotation, but this is to keep consistency with early_ioremap() which
does not have a 'memremap' flavor.
