xen/arm: Add relinquish_p2m_mapping to remove reference on every mapped page

This function will be called when the domain relinquishes its memory.
It removes refcount on every mapped page to a valid MFN.

Currently, Xen doesn't take reference on every new mapping but only for foreign
mapping. Restrict the function only on foreign mapping.
