ALSA: oxfw: add support for APOGEE duet FireWire

[ Upstream commit fba43f454cdf9caa3185219d116bd2a6e6354552 ]

This commit adds support for APOGEE duet FireWire, launched 2007, already
discontinued. This model uses Oxford Semiconductor FW971 as its
communication engine. Below is information on Configuration ROM of this
unit. The unit supports some AV/C commands defined by Audio subunit
specification and vendor dependent commands.
