Xen: drop exports of {set,clear}_foreign_p2m_mapping()
They're only used internally, and the layering violation they contain
(x86) or imply (Arm) of calling HYPERVISOR_grant_table_op() strongly
advise against any (uncontrolled) use from a module. The functions also
never had users except the ones from drivers/xen/grant-table.c forever
since their introduction in 3.15.
