Subject: [PATCH v2 2/5] dt-bindings: devfreq: rk3399_dmc: Add rockchip, pmu phandle.

From: Enric Balletbo i Serra <enric.balletbo@...labora.com>

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.
