ARM: riscpc: use GENERIC_IRQ_MULTI_HANDLER
This is one of the last platforms using the old entry path. While this code path is spread over a few files, it is fairly straightforward to convert it into an equivalent C version, leaving the existing algorithm and all the priority handling the same. Unlike most irqchip drivers, this means reading the status register(s) in a loop and always handling the highest-priority irq first. The IOMD_IRQREQC and IOMD_IRQREQD registers are not actaully used here, but I left the code in place for the time being, to keep the conversion as direct as possible. It could be removed in a cleanup on top.
