[PATCH v3 5/5] arm64: dts: rockchip: Add HDMI0 PHY PLL clock source to VOP2 on RK3588

[Cristian Ciocaltea]

VOP2 on RK3588 is able to use the HDMI PHY PLL as an alternative and
more accurate pixel clock source to improve handling of display modes up
to 4K at 60Hz on video ports 0, 1 and 2.

For now only HDMI0 output is supported, hence add the related PLL clock.
