Asha Talambedu 39cc4081e3 ASoC: tegra: Add shutdown callback

- Added mutex protection for init_done flag reads in
  mixer control callbacks relevant to "ADSP init". Otherwise
  during shutdown sequence that includes alsa store service,
  this leads to inconsistent behaviour
- Shutdown callback is added to deinit ADSP OS during
  abrupt shutdown.
- In case ADSP OS is crashed during boot/boot has not
  started yet, shutdown does not issue OS deinit as
  init is not complete yet
