arm64: dts: rockchip: Update CPU OPP voltages in RK356x SoC dtsi

Browse source

Update the lower/upper voltage limits and the exact voltages for the Rockchip
RK356x CPU OPPs, using the most conservative values (i.e. the highest per-OPP
voltages) found in the vendor kernel source. [1]

Using the most conservative per-OPP voltages ensures reliable CPU operation
regardless of the actual CPU binning, with the downside of possibly using
a bit more power for the CPU cores than absolutely needed.

Additionally, fill in the missing "clock-latency-ns" CPU OPP properties, using
the values found in the vendor kernel source. [1]
