Subject: [PATCH v2 32/57] irqdomain: ppc: Switch to irq_domain_create_*()
irq_domain_add_*() interfaces are going away as being obsolete now.
Switch to the preferred irq_domain_create_*() ones. Those differ in the
node parameter: They take more generic struct fwnode_handle instead of
struct device_node. Therefore, of_fwnode_handle() is added around the
original parameter.
Note some of the users can likely use dev->fwnode directly instead of
indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not
guaranteed to be set for all, so this has to be investigated on case to
case basis (by people who can actually test with the HW).
