The Allwinner H616/H618 SoCs have different OPP tables per SoC version and die revision. The SoC version is stored in NVMEM, as before, though encoded differently. The die revision is in a different register, in the SRAM controller. Firmware already exports that value in a standardised way, through the SMCCC SoCID mechanism. We need both values, as some chips have the same SoC version, but they don't support the same frequencies and they get differentiated by the die revision. Add the new compatible string and tie the new translation function to it. This mechanism not only covers the original H616 SoC, but also its very close sibling SoCs H618 and H700, so add them to the list as well.

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 reStructuredText 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.
