soc: qcom: pmic_glink: Add support for SOCCP remoteproc channels

System On Chip Control Processor (SOCCP) is a subsystem that can have
battery management firmware running on it to support Type-C/PD and
battery charging. SOCCP does not have multiple PDs and hence PDR is not
supported. So, if the subsystem comes up/down, rpmsg driver would be
probed or removed. Use that for notifying clients of pmic_glink for
PDR events.

Add support for battery management FW running on SOCCP by adding the
"PMIC_RTR_SOCCP_APPS" channel name to the rpmsg_match list and
updating notify_clients logic.
