irqdomain: Use irq_domain_get_of_node() instead of direct field access
The struct irq_domain contains a "struct device_node *" field (of_node) that is almost the only link between the irqdomain and the device tree infrastructure. In order to prepare for the removal of that field, convert all users to use irq_domain_get_of_node() instead.
