arm64: dts: qcom: sc7180: Delete kingoftown-rev0

The earliest kingoftown that I could find in my pile of boards was
-rev2 and even that revision looks pretty rough (plastics on the case
are very unfinished). Though I don't actually have details about how
many -rev0 devices were produced, I can't imagine anyone still using
one. Let's delete support.
