    xen/arm: Use vmap_contig instead of __vmap where it's possible
    
    Currently the arm code uses __vmap function in few parts to map
    physically contiguous pages, vmap_contig was introduced recently
    and does the same because it's a wrapper for __vmap, so use the
    latter instead of the direct __vmap function.
