c839d521c431: auich: Always enable PCI bus mastering.
Without it, the device can't operate at all. Whether or not this is
enabled already is firmware dependent. It was off under QEMU when used
with "-soundhw ac97" and this makes the driver work there.
Fixes #10551 where the syslog shows that this can also happen on real
hardware that is otherwise fully configured.
