irqchip: mips-gic: Remove gic_set_dual_edge()
Remove the gic_set_dual_edge() function in favour of using the new
change_gic_dual() accessor function which provides equivalent
functionality. This also allows us to remove the gic_update_bits()
function which gic_set_dual_edge() was the last user of, along with the
GIC_INTR_OFS() & GIC_INTR_BIT() macros.
