[PATCH] arm64: dts: qcom: sc8180x: Add SLPI remoteproc node

[Val Packett]

The Sensors Low-Power Island remoteproc hosts the Sensor Hub firmware
that Linux userspace (hexagonrpcd) can talk to.

Describe the SLPI node for the SC8180X SoC.

Forgor about committing and sending this while submitting the Surface
Pro X series v1..

Since this is independent and simple while that series is waiting for
comments about the multi-PCIe situation, let's get this in first?

Thanks,
~val
