[ Upstream commit fb76b0fae3ca880363214e1dcd6513ab8bd529e7 ]
According to the R-Car Series, 3rd Generation Hardware User’s Manual Rev. 2.30, the System CPU cores on R-Car E3 do not have their own power supply, but use the common internal power supply (typical 1.03V).
Hence remove the "opp-microvolt" properties from the Operating Performance Points table. They are optional, and unused, when none of the CPU nodes is tied to a regulator using the "cpu-supply" property.
