Subject: [PATCH 3/3] arm64: dts: rockchip: add phandles to muxed i2c buses on rk3368-lion

From: Jakob Unterwurzacher <jakob.unterwurzacher@...obroma-systems.com>

Other DTS files that include the dtsi will want to to add children
to the i2c buses from the i2c-mus. Without a label they would have to
specify the full path.

[add phandles for first mux as well]
