Now that the GIC properly uses IRQ domains, kill off the per-platform
routing tables that were used to make the GIC appear transparent.
This includes:
- removing the mapping tables and the support for applying them,
- moving GIC IPI support to the GIC driver,
- properly routing the i8259 through the GIC on Malta, and
- updating IRQ assignments on SEAD-3 when the GIC is present.
Platforms no longer will pass an interrupt mapping table to gic_init.
Instead, they will pass the CPU interrupt vector (2 - 7) that they
expect the GIC to route interrupts to. Note that in EIC mode this
value is ignored and all GIC interrupts are routed to EIC vector 1.

Use a simple IRQ domain for the MIPS GIC. Remove the gic_platform_init
callback as it's no longer necessary for it to set the irqchip.

Implement an irq_set_type callback for the GIC which is used to set
the polarity and trigger type of GIC interrupts.

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.
