MIPS: Rename mips_cpu_intc_init() -> mips_cpu_irq_of_init()

mips_cpu_intc_init() is used for DT-based initialization of the CPU
IRQ domain.  Give it a more appropriate name.

+On MIPS the mips_cpu_irq_of_init() helper can be used to initialize the 8 CPU
 IRQs from a devicetree file and create a irq_domain for IRQ controller.
 
 With the irq_domain in place we can describe how the 8 IRQs are wired to the
