We can have multiple FDT irqchip drivers to be probed when a RISC-V system has different types of interrupt controller in a hierarchy. This will be certainly the case when a RISC-V system has both RISC-V AIA IMSIC and RISC-V AIA APLIC implemented. We extend simple FDT irqchip framework to allow multiple FDT irqchip drivers to be used for same RISC-V platform.
