irqchip: Select downstream irqchip drivers for LoongArch CPU

Browse source 
LoongArch irqchips have a fixed hierarchy which currently can't be
described by ACPI tables, so upstream irqchip drivers call downstream
irqchip drivers' initialization directly. As a result, the top level
(CPU-level) irqchip driver should explicitly select downstream drivers
to avoid build errors.
