powerpc: Switch irq_domain_add_nomap() to use fwnode

All irq_domain_add_*() functions are going away. PowerPC is the only
user of irq_domain_add_nomap() and there is no irq_domain_create_nomap()
complement.

Therefore, to align with the rest of the kernel, rename
irq_domain_add_nomap() to irq_domain_create_nomap() and accept a
fwnode_handle instead of a device_node.

 当硬件中的hwirq号是可编程的时候，就可以采用无映射类型。 在这种情况下，最好将
 Linux IRQ号编入硬件本身，这样就不需要映射了。 调用irq_create_direct_mapping()
