I noticed that I didn't document the new compatible string I'm using,
qcom,sc7180-qmp-usb3-dp-phy, ugh.

Should I copy the whole file over and make a new document for the new
compatible string? That feels like the better solution vs. making this
binding have min/max stuff where it fails to enforce the DP part of the
phy. We can delete this binding once the kernel tree isn't using it,
right?
