DeviceTree bindings have stable ABI=2E Although they're currently=20
only used internally in Kernel=2E I don't think it's a good idea
to rename existing bindings=2E

Also, Loongson64C/64G/64R never came to a part of Loongson's
official naming=2E I doubt if end users will recognize these names=2E

I'd prefer keep naming as is=2E It's really not a big deal=2E

Thanks=2E
