The BAU on UV4 does not need to maintain the payload queue tail pointer. Do not initialize the tail pointer MMR on UV4. Note that write_payload_tail is not an abstracted BAU function since it is an operation specific to pre-UV4 versions. Then we must switch on the UV version to control its usage, for which we use uvhub_version rather than is_uv*_hub because it is quicker/more concise.
