Compared to the existing Allwinner H6 OPP scheme, the H616 uses a similar NVMEM based mechanism to determine the silicon revision, which is required to select the right frequency / voltage pair for the OPPs. However it limits the maximum frequency for some speed bins, also seems to not support all frequencies in all speed bins, which requires us to introduce the opp-supported-hw property. Add this property to the list of allowed properties, also drop the requirement for the revision specific opp-microvolt properties, since they might not be needed if using opp-supported-hw. Also use to opportunity to adjust some wording, and drop a sentence referring to the Linux driver and the OPP subsystem. Shorten the existing example and add another example, showcasing the opp-supported-hw property.

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.
