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@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.
