According to YAML validation, and for a future patchset putting this
xo_board reference clock to use as VCO reference parent, add the missing
clock to dsi_phy0.
Fixes: 5a9fc531f6ec ("ARM: dts: msm8974: add display support")

And just to confirm on MSM8974 "ref" is supposed to be 19.2Mhz?

Yes, the 28nm-hpm driver (unlike the 28nm-8960 driver for apq8064) uses
19.2MHz for its hardcoded VCO_REF_CLK_RATE calculations.
Perhaps we should reword the commit message to read "... add the missing
19.2MHz xo clock ...".
