Subject: [PATCH v20 12/41] ASoC: qdsp6: q6afe: Increase APR timeout

For USB offloading situations, the AFE port start command will result in a
QMI handshake between the Q6DSP and the main processor.  Depending on if
the USB bus is suspended, this routine would require more time to complete,
as resuming the USB bus has some overhead associated with it.  Increase the
timeout to 3s to allow for sufficient time for the USB QMI stream enable
handshake to complete.
