Subject: [PATCH v3 1/5] arm64: dts: rockchip: Use phandle for i2c_lvds_blc on rk3368-lion haikou

From: Heiko Stuebner <heiko.stuebner@...rry.de>

i2c@0 on i2cmux2 does already have a phandle i2c_lvds_blc defined.

Use this one instead of replicating the hierarchy again, as this might
result in strange errors if the lion dtsi is changed at some point
in the future.
