soc: qcom: smd-rpm: Match rpmsg channel instead of compatible
There is an ever growing list of compatibles in the smd-rpm.c driver.
A fallback compatible would help here but would still require keeping
the current list around for backwards compatibility.
As an alternative, let's switch the driver to match the rpmsg_device_id
instead, which is always "rpm_requests" on all platforms. Add a check
to ensure that there is a device tree node defined for the device since
otherwise the of_platform_populate() call will operate on the root node (/).
Similar approaches with matching rpmsg_device_id are already used in
qcom_sysmon, qcom_glink_ssr, qrtr, and rpmsg_wwan_ctrl.
