irqchip: mips-gic: Let the core set struct irq_common_data affinity 

gic_set_affinity() manually copies the provided cpumask to the struct
irq_common_data affinity field, returning IRQ_SET_MASK_OK_NOCOPY in
order to prevent the core code from doing that.

We can instead simply let the core code do it for us, by returning
IRQ_SET_MASK_OK instead of IRQ_SET_MASK_OK_NOCOPY & doing the copy
ourselves.
