irqchip/gic-v3-its: Use irq_domain_create_hierarchy()
Use the irq_domain_create_hierarchy() helper to create the hierarchical domain, which both serves as documentation and avoids poking at irqdomain internals. Note that the domain host_data was first set to the struct its_node during allocation only to immediately be overwritten with the struct msi_domain_info.
