[PATCH] arm64/xen: redefine xen_remap on arm64

[Chen Baozi]

xen_remap used to be defined as ioremap_cached on arm64. In commit
c04e8e2fe, a new ioremap_cache was implemented, and ioremap_cached
was deleted, while xen_remap stays the same. This would lead to
the failure when building with CONFIG_HVC_XEN. Redefined xen_remap
on arm64 as ioremap_cache on arm64 to fix it.
