hw/loongarch: Add acpi ged support

Browse source 
Loongarch virt machine uses general hardware reduces acpi method, rather
than LS7A acpi device. Now only power management function is used in
acpi ged device, memory hotplug will be added later. Also acpi tables
such as RSDP/RSDT/FADT etc.

The acpi table has submited to acpi spec, and will release soon.
