    include: make domain_page.h's stubs properly use type-unsafe MFN <-> virt 
helpers
    
    The first of the commits referenced below didn't go far enough, and the
    2nd of them, while trying to close (some of) the gap, wrongly kept using
    the potentially type-safe variant. This is getting in the way of new
    ports preferably not having any type-unsafe private code (and in
    particular not having a need for any overrides in newly introduced
    files).
    
    Fixes: 41c48004d1d8 ("xen/mm: Use __virt_to_mfn in map_domain_page instead 
of virt_to_mfn")
    Fixes: f46b6197344f ("xen: Convert page_to_mfn and mfn_to_page to use 
typesafe MFN")
