IRQCHIP: irq-mips-gic: Add new functions to start/stop the GIC counter
We add new functions to start and stop the GIC counter since there are no guarantees the counter will be running after a CPU reset. The GIC counter is stopped by setting the 29th bit on the GIC Config register and it is started by clearing that bit.
