irqdomain: Make irq_domain_create_hierarchy() an inline

There is no reason to export the function as an extra symbol. It is
simple enough and is just a wrapper to already exported functions.

Therefore, switch the exported function to an inline.

- * @fwnode:	Optional fwnode of the interrupt controller
