Add fan-shutdown-percent property, used to describe fan RPM in percent set during shutdown. This is used to keep the fan running at fixed RPM after the kernel shut down, which is useful on hardware that does keep heating itself even after the kernel did shut down, for example from some sort of management core. The current behavior of pwm-fan is to unconditionally stop the fan on shutdown, which is not always the safe and correct thing to do, so let the hardware description include the expected behavior.

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.
