This was needed to look up a remoteproc structure pointer used when registering for notifications in the original IPA notification mechanism. Remoteproc provides a more generic SSR notifier system, and the IPA driver switched over to it last summer, but this remoteproc phandle dependency was not removed at that time. Get rid of the IPA remoteproc pointer and stop requiring the phandle be specified. This avoids a link error (rproc_put() not defined) for certain configurations.
