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.
The HDMI1 PHY PLL clock source cannot be added directly to vop node in
rk3588-base.dtsi, along with the HDMI0 related one, because HDMI1 is an
optional feature and its PHY node belongs to a separate (extra) DT file.
Therefore, add the HDMI1 PHY PLL clock source to VOP2 by overwriting its
clocks & clock-names properties in the extra DT file.
