ASoC: codecs: handle device disconnect during SSR

During SSR, when usbc analog device is disconnected, the
respective disconnect interrupt is not handled and hence userspace
is not notified. When ADSP recovers, fsa driver sends a disconnect
notification. So handle device disconnect and notify jack/userspace
through this notification.
