irqdomain: Do irq_find_mapping and set_type for hierarchy irqdomain in case OF

It is possible to call irq_create_of_mapping to create/translate the
same IRQ from DT for multiple times. Perform irq_find_mapping check
and set_type for hierarchy irqdomain in irq_create_of_mapping() to
avoid duplicate these functionality in all outer most irqdomain.
