In order to support irqchip_in_kenrel method, split loongarch extioi
emulation driver into two parts, extioi common and extioi TCG driver.
LoongArch extioi common driver includes vmstate and property interface,
also vmstate load and store interface is defined in extioi common driver.

In future LoongArch extioi kvm driver can inherit from extioi common
driver.
