H A Dsun50i-h6-orangepi-3.dtsebae33c3 Mon Apr 20 08:00:18 CDT 2020 Clément Péron <peron.clem@gmail.com> arm64: dts: allwinner: h6: Enable CPU opp tables for Orange Pi 3

Enable CPU opp tables for Orange Pi 3.

This needs to change the CPU regulator max voltage to fit
the OPP table.

Also add the ramp-delay information to avoid any out of spec
running as the regulator is slower at reaching the voltage
requested compare to the PLL reaching the frequency.

There is no such information for AXP805 but similar PMIC (AXP813)
has a DVM (Dynamic Voltage scaling Management) ramp rate equal
to 2500uV/us.
