msm: msm_dsps: Disable the DSPS watchdog before shutdown

The DSPS watchdog timer continues counting even after
the DSPS is shutdown. This may cause a spurious watchdog
interrupt after the DSPS is powered up, before the software
running on the processor can re-init the watchdog. Disable
the watchdog before shutting down the watchdog.
