Loongarch pch msi intc connects to extioi controller, the range of irq number is 64-255. Add a property for irqbase, so that we can compute the irq offset from the view of pch_msi controller with the method: msi vector (from view of upper extioi intc) - irqbase Signed-off-by: Mao Bibo <maobibo@loongson.cn> Message-Id: <20220701030740.2469162-1-maobibo@loongson.cn> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
