Neil Armstrong b190056fa9 arm64: dts: meson-g12a: add cpus OPP table
Add the OPP table taken from the vendor u200 and u211 DTS.

The Amlogic G12A SoC seems to available in 3 types :
- low-speed: up to 1,8GHz
- mid-speed: up to 1,908GHz
- high-speed: up to 2.1GHz

And the S905X2 opp voltages are slightly higher than the S905D2
OPP voltages for the low-speed table.

This adds the conservative OPP table with the S905X2 higher voltages
and the maximum low-speed OPP frequency.

The values were tested to be stable on an Amlogic U200 Reference Board,
SeiRobotics SEI510 and X96 Max Set-Top-Boxes running the arm64 cpuburn
at [1] and cycling between all the possible cpufreq translations and
checking the final frequency using the clock-measurer, script at [2].

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
