irqdomain: Introduce irq_domain_create_{linear, tree}
Just like we have irq_domain_add_{linear,tree} to create a irq domain
identified by an of_node, introduce irq_domain_create_{linear,tree}
that do the same thing, except that they take a struct fwnode_handle.
Existing functions get rewritten in terms of the new ones so that
everything keeps working as before (and __irq_domain_add is now
fwnode_handle based as well).
