Lenovo Ideapad Z560 has a mute LED that is controlled via EAPD pin
0x1b on CX20585 codec. (EAPD bit on corresponds to mute LED on.)
The machine doesn't need other EAPD, so the fixup concentrates on
controlling EAPD 0x1b following the vmaster state (but inversely).

Commit f5866db6 (virtio_console: enable VQs early) tried to make
sure that DRIVER_OK was set when virtio_console started using its
virtqueues. Doing this in add_port(), however, means that we try
to set DRIVER_OK again when when a port is dynamically added after
the probe function is done.
Let's move virtio_device_ready() to the probe function just before
trying to use the virtqueues instead. This is fine as nothing can
fail inbetween.

always returns 0 whether or not we completed the poll quantum.
Fix this by returning either 0 when we did complete the TX ring reclaim,
