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.

The No Map mapping is to be used when the hwirq number is

programmable in the hardware.  In this case it is best to program the

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()
