irqchip: mips-gic: Remove unnecessary globals

Now that all GIC interrupt routing and handling logic is in the GIC
driver itself, un-export variables/functions which are no longer used
outside the GIC driver.  This also allows us to remove gic_compare_int
and combine gic_get_int_mask with gic_get_int since these interfaces
are no longer used.
