Disable Ethernet switch reset GPIO with ZII platforms that have it enabled. HW switch reset results in a reset of the copper PHYs inside of the switch. We want to avoid this reset of the copper PHYs in the switch as this results in unnecessary broader network disruption on a soft reboot of the application processor. With the HW GPIO removed, the switch driver still performs a soft reset of the switch core which has been shown to sufficiently meet our needs with other ZII platforms that do not have the HW switch reset GPIO defined.

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.
