Create a serdes_get_lane() method in the mv88e6xxx operations structure. Use it instead of calling the different implementations. Also change the methods so that their return value is used only for error. The lane number is put into a place referred to by a pointer given as argument. If the port does not have a lane, return -ENODEV. Lanes are phy addresses, so use u8 as their 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 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.
