[PATCH v2 3/9] arm64: dts: rockchip: Add missing clock "hclk" for RK3588 eDP1 nodes.

The RK3588 eDP controller needs the video datapath clock "hclk" to work
well. Previously, it works without explicitly adding this clock because
the 'rockchip,vo-grf = <&vo1_grf>' property implicitly enables HCLK_VO1.
