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

- Redesign and improve remote heap management.
- Add static PD restart support for audio and sensors PD using
  PDR framework.
- Add changes to support multimode invocation ioctl request. This
  ioctl call facilitates multiple types of requests from user including
  CRC check, performance counters, shared context bank usage, etc.
  This series also carries patch to save and restore interrupted
  context.
- 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
- Add wakelock management support
- Add DSP signalling support
- Add check for untrusted applications and allow trusted processed to
  offload to system unsigned PD.
