[PATCH v4 1/2] arm64: dts: rockchip: add "rockchip, grf" property for RK3399 PMUCRU/CRU

The structure rockchip_clk_provider needs to refer the GRF regmap
in somewhere, if the CRU node has not "rockchip,grf" property,
calling syscon_regmap_lookup_by_phandle will return an invalid GRF
regmap, and the MUXGRF type clock will be not supported.
Therefore, we need to add them.
