CONFIG_XEN_PV breaks xen_create_contiguous_region on ARM
commit f9005571701920551bcf54a500973fb61f2e1eda upstream.
xen_create_contiguous_region has now only an implementation if
CONFIG_XEN_PV is defined. However, on ARM we never set CONFIG_XEN_PV but
we do have an implementation of xen_create_contiguous_region which is
required for swiotlb-xen to work correctly (although it just sets
*dma_handle).
[backport: remove change to xen_remap_pfn]
