This patch serie extend the PL08x driver to allow using it with
sound drivers. Sound drivers require the cyclic transfer mode and
that tx_status give reliable results.

* Patch 1 is a trivial fix
* Patch 2 implement the cyclic mode needed by sound drivers
* Patch 3 fix the tx_status implementation to get reliable results
