Can we stop adding "qcom,sc7280" to the board compatible string? It
looks out of place. It's the compatible for the SoC and should really be
the compatible for the /soc node.

Sometimes '-regulator' is left out. Is that intentional? I suppose it
would be better if every node had regulator postfix, but it may be too
long of a node name?
