The function mfn_to_p2m_entry will be extended in a following patch to handle
p2m_type_t. It will break compilation because p2m_type_t is not defined
(interdependence between includes).
It's easier to move the function in arch/arm/p2m.c and it's not harmful as the
function is only used in this file.
