Stefano Stabellini 491636a88c CONFIG_XEN_PV breaks xen_create_contiguous_region on ARM 
commit f900557170 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]

Cc: <stable@vger.kernel.org> # 4.12
Fixes: 1662439081 ("xen: create xen_create/destroy_contiguous_region() stubs for PVHVM only builds")
