Add support for the Texas Instruments INA228 Ultra-Precise Power/Energy/Charge Monitor. The INA228 is very similar to the INA238 but offers four bits of extra precision in the temperature, voltage and current measurement fields. It also supports energy and charge monitoring, the latter of which is not supported through this patch. While it seems in the datasheet that some constants such as LSB values differ between the 228 and the 238, they differ only for those registers where four bits of precision have been added and they differ by a factor of 16 (VBUS, VSHUNT, DIETEMP, CURRENT). Therefore, the INA238 constants are still applicable with regard to the bit of the same significance.

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.
