mm: clean up is_device_*_page() definitions

Refactor is_device_{public,private}_page() with is_pci_p2pdma_page() to
make them all consistent in depending on their respective config options
even when CONFIG_DEV_PAGEMAP_OPS is enabled for other reasons.  This
allows a little more compile-time optimisation as well as the conceptual
and cosmetic cleanup.
