arm/xen: Export phys_to_mach to fix Xen module link errors

Various xen drivers fail to link when built as modules with the following
error:

ERROR: "phys_to_mach" [drivers/xen/xen-gntalloc.ko] undefined!
ERROR: "phys_to_mach" [drivers/net/xen-netfront.ko] undefined!
ERROR: "phys_to_mach" [drivers/net/xen-netback/xen-netback.ko] undefined!
ERROR: "phys_to_mach" [drivers/block/xen-blkfront.ko] undefined!

The mfn_to_pfn and pfn_to_mfn functions get inlined in these modules and
those functions require phys_to_mach.  Export the symbol to fix the link
errors.
