The MDIO device reset line is optional and now that gpiod_get_optional() returns proper value when GPIO support is compiled out, there is no reason to use fwnode_get_named_gpiod() that I plan to hide away. Let's switch to using more standard gpiod_get_optional() and gpiod_set_consumer_name() to keep the nice "PHY reset" label. Also there is no reason to only try to fetch the reset GPIO when we have OF node, gpiolib can fetch GPIO data from firmwares as well.

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.
