Subject: [PATCH 73/78] hw/loongarch: Add KVM extioi device support
Added extioi interrupt controller for kvm emulation.
The main process is to send the command word for
creating an extioi device to the kernel.
When the VM is saved, the ioctl obtains the related
data of the extioi interrupt controller in the kernel
and saves it. When the VM is recovered, the saved data
is sent to the kernel.
