arm64: dts: qcom: Add rpm-proc node for GLINK gplatforms

Rather than having the RPM GLINK channels as the only child of a dummy
top-level rpm-glink node, switch to representing the RPM as remoteproc
like all the other remoteprocs (modem DSP, ...).

This allows assigning additional subdevices to it like the MPM
interrupt-controller or rpm-master-stats.
