memremap: validate the pagemap type passed to devm_memremap_pages
Most pgmap types are only supported when certain config options are
enabled. Check for a type that is valid for the current configuration
before setting up the pagemap. For this the usage of the 0 type for
device dax gets replaced with an explicit MEMORY_DEVICE_DEVDAX type.
