Add support for the RTC's NVRAM using the standard nvmem support that is part of the Linux RTC framework. This driver already has a sysfs attribute that provides access to the RTC's NVRAM as a single 16-bit value. Some chips have more than two bytes of NVRAM, so this will not work for them. It's also non-standard. This sysfs attribute is left in for backward compatibility, but will only be able to read the first two bytes of NVRAM. The nvmem interface will allow access to all NVRAM, e.g. eight bytes on the isl1218.

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.
