ARM: dts: qcom: Add rpm-proc node for SMD platforms

Browse Source 
Rather than having the RPM SMD channels as the only child of a dummy
SMD node, switch to representing the RPM as remoteproc like all the
other remoteprocs (WCNSS, modem DSP).

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