arm64: dts: rockchip: Enable HDMI PHY clk provider on rk3576

commit aba7987 upstream.

As with the RK3588 SoC, the HDMI PHY PLL on RK3576 can be used as a more
accurate pixel clock source for VOP2, which is actually mandatory to
ensure proper support for display modes handling.

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