xen: arm: make p2m operations NOPs
This makes common code less ifdef-y and is consistent with PVHVM on x86. Also note that phys_to_machine_mapping_valid should take a pfn argument and make it do so. Add __set_phys_to_machine, make set_phys_to_machine a simple wrapper (on systems with non-nop implementations the outer one can allocate new p2m pages). Make __set_phys_to_machine check for identity mapping or invalid only.
