Currently we support SERDES on the Topaz family in a limited way: no IRQs and the cmode is not writable, thus the mode is determined by strapping pins. Marvell's examples though show how to make cmode writable on port 5 and support SGMII autonegotiation. It is done by writing hidden registers, for which we already have code. This patch adds support for making the cmode for the SERDES port writable on the Topaz family, via a new chip operation, .port_set_cmode_writable, which is called from mv88e6xxx_port_setup_mac just before .port_set_cmode. SERDES IRQs are also enabled for Topaz. Tested on Turris Mox.

README
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.
