A clock input to a device should be named after the usage in the device, not after the clock that drives it. On the rk3568 the same clock is driven by the HPLL. To fix that, this patch renames the vpll clock to ref clock. The clock name "vpll" is left for compatibility to old device trees.

The last patch removed the CLK_SET_RATE_PARENT flag from the pixel clocks which means the hpll is not changed on pixel clock changes. In order to allow the HDMI controller to set a suitable PLL rate we now add the CLK_SET_RATE_PARENT flag to the HDMI reference clock. With this the flow becomes: 1) HDMI controller driver sets the rate to its pixel clock which means hpll is set to the pixel clock 2) VOP2 driver sets dclk_vop[012] to the pixel clock. As this can't change the hpll clock anymore this means only the divider is adjusted to the desired value of dividing by one.
