soc/mediatek/mt8186: add GIC pre-initialization function
GIC (generic interrupt controller) defines architectural requirements
for handling all interrupt sources and common interrupt controller
programming interface.
GIC needs to be pre-initialized on MT8186, so we add this initialize
function.
TEST=build pass
