This adds the common Qualcomm helpers to tie in subsystem restart notifications
with the ADSP and Modem PILs and then adds a driver for the "glink_ssr" channel
to propagate these notifications.

This is needed on GLINK RPM enabled platforms to have the RPM reset the state
of the communication channels to the peripherals, allowing them to be restarted
without the RPM crashing due stale FIFO data.
