Bibo Mao	c642ddf19b	hw/loongarch/virt: Add reset support for kernel irqchip ... When system reboot, interrupt controller is restored to initial state. However if interrupt controller extioi/ipi/pch_pic is emulated in kernel, it should notify kvm to do so. Here suspend and restore API is used for reset, set initial state in qemu user space and restore API is used to notify kvm to reload register state.
