irqchip: mips-gic: Remove platform irq_ack/irq_eoi callbacks

There's no need for platforms to have their own GIC irq_ack/irq_eoi
callbacks.  irq_ack need only clear the GIC's edge detector on
edge-triggered interrupts and there's no need at all for irq_eoi.
Also get rid of the mask_ack callback since it's not necessary either.
