    xen: arm: allow virt_to_maddr to take either a pointer or an integer
    
    This seems to be expected by common code which passes both pointers and
    unsigned long as virtual addresses. The latter case in particular is in
    init_node_heap() under a DIRECTMAP_VIRT_END #ifdef, which is why it hasn't
    affected us yet (but will in a subsequent patch).
    
    The new prototypes match the x86 versions apart from using vaddr_t instead 
of
    unsigned long.
