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.
