To enable kvm_irqchip_in_kernel option on LoongArch virt machine
platform, property irqchip-in-kernel is added on irqchips including
ExtIOI, IPI, PCH_PCI and PCH_MSI irqchip.
If property irqchip-in-kernel is set, there is special operations with
irqchips in such fields:
1. During irqchip object realization, kvm_create_device() is used here
to create irqchip in KVM kernel.
2. Add pre_save and post_load function, where register states can be
get and set from KVM kernel.
3. Interrupt injection to kernel, IRQ line intterupt is injected with
API kvm_set_irq() and MSI intterrupt is injected with API
kvm_irqchip_send_msi().
