DeviceTree bindings have stable ABI. Although they're currently only used internally in Kernel. I don't think it's a good idea to rename existing bindings. Also, Loongson64C/64G/64R never came to a part of Loongson's official naming. I doubt if end users will recognize these names. I'd prefer keep naming as is. It's really not a big deal.
