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.
