device property: Add iomap to fwnode operations
Add iomap() fwnode operation to implement fwnode_iomap() through fwnode operations, moving the code in fwnode_iomap() to OF framework. Note that the IS_ENABLED(CONFIG_OF_ADDRESS) && is_of_node(fwnode) check is needed for Sparc that has its own implementation of of_iomap anyway. Let the pre-compiler to handle that check.
