References: git-fixes

According to the RZ/G Series, 2nd Generation Hardware User’s Manual
Rev. 1.11, the System CPU cores on RZ/G2E 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.

Fixes: 231d8908a66fa98f ("arm64: dts: renesas: r8a774c0: Add OPPs table for cpu devices")
