Introduce support for configuring the master/slave role of PHYs based on the `timing-role` property in the device tree. While this functionality is necessary for Single Pair Ethernet (SPE) PHYs (1000/100/10Base-T1) where hardware strap pins may be unavailable or incorrectly set, it works for any PHY type.

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.
