[RFC PATCH 02/10] dt-bindings: devfreq: rk3399_dmc: Add rockchip,pmu phandle.

From: Enric Balletbo i Serra
Date: Mon May 14 2018 - 17:18:55 EST

The Rockchip DMC (Dynamic Memory Interface) needs to access to the PMU
general register files to know the DRAM type, so add a phandle to the
syscon that manages these registers.
