ACPI ged is used for power management on LoongArch virt platform, in general it is parsed from acpi table. However if system boot directly from elf kernel, no UEFI bios is provided and acpi table cannot be used also. Here acpi ged pm register is exposed with FDT table, it is compatbile with syscon method in FDT table, only that acpi ged pm register is accessed with 8-bit mode, rather in 32-bit mode.
