IRQCHIP: mips-gic: Add function for retrieving FDC IRQ
Add a function to the MIPS GIC driver for retrieving the Fast Debug Channel (FDC) interrupt number, similar to the existing ones for the timer and perf counter interrupts. This will be used by platform implementations of get_c0_fdc_int() if a GIC is present. A workaround exists for interAptiv and proAptiv which claim to be able to route the FDC interrupt but don't seem to be able to in practice (at least on Malta).
