Subject: [PATCH 2/4] arm64: dts: rockchip: Enable HDMI1 PHY clk provider on
 RK3588

Since commit c4b09c562086 ("phy: phy-rockchip-samsung-hdptx: Add clock
provider support"), the HDMI PHY PLL can be used as an alternative and
more accurate pixel clock source for VOP2 to improve display modes
handling on RK3588 SoC.

Add the missing #clock-cells property to allow using the clock provider
functionality of HDMI1 PHY.
