ASoC: wcd-spi: fix clock disable request during shutdown

It is possible that there could be pending delayed request to disable
the clock while the manager driver has already raised shutdown event.
In such cases, the delayed clock disable request will be made after
shutdown, resulting in unclocked access on the SPI bus. Fix this by
intercepting the shutdown event to flush the clock votes and disable
the clock.
