This patch series adds the listed features that have been missing
in upstream fastRPC driver.

- Add early wakeup support to allow DSP user to send early response
  to CPU and improve fastrpc performance.
- Add polling mode support with which driver polls on memory to avoid
  CPU from going to low power modes.
- Add notifications frameworks to provide users with the DSP PD status
  notifications.
- Add a control mechanism to allow users to clean up DSP user PD

This patch series depends on multimode support series:
