remoteproc: add IPA notification to q6v5 driver
Set up a subdev in the q6v5 modem remoteproc driver that generates event notifications for the IPA driver to use for initialization and recovery following a modem shutdown or crash. A pair of new functions provides a way for the IPA driver to register and deregister a notification callback function that will be called whenever modem events (about to boot, running, about to shut down, etc.) occur. A void pointer value (provided by the IPA driver at registration time) and an event type are supplied to the callback function. One event, MODEM_REMOVING, is signaled whenever the q6v5 driver is about to remove the notification subdevice. It requires the IPA driver de-register its callback. This sub-device is only used by the modem subsystem (MSS) driver, so the code that adds the new subdev and allows registration and deregistration of the notifier is found in "qcom_q6v6_mss.c".
