Add device-tree support for the MIPS GIC.  With DT, no per-platform
static device interrupt mapping is supplied and instead all device
interrupts are specified through the DT.  The GIC-to-CPU interrupts
must also be specified in the DT.

Platforms using DT-based probing of the GIC need only supply the
GIC_NUM_INTRS and, if necessary, MIPS_GIC_IRQ_BASE values and
call of_irq_init() with an of_device_id table including the GIC.

Currenlty only legacy and vecotred interrupt modes are supported.

Can you move this to drivers/irqchip and use the IRQCHIP_DECLARE()
macro to define the entry point?

Sure.  I was planning on doing this later, but I don't see why it
couldn't be done now though.
