Add driver for the MaxLinear GSW1xx family of Ethernet switch ICs which are based on the same IP as the Lantiq/Intel GSWIP found in the Lantiq VR9 and Intel GRX MIPS router SoCs. The main difference is that instead of using memory-mapped I/O to communicate with the host CPU these ICs are connected via MDIO (or SPI, which isn't supported by this driver). Implement the regmap API to access the switch registers over MDIO to allow reusing lantiq_gswip_common for all core functionality. The GSW1xx also comes with a SerDes port capable of 1000Base-X, SGMII and 2500Base-X, which can either be used to connect an external PHY or SFP cage, or as the CPU port. Support for the SerDes interface is implemented in this driver using the phylink_pcs interface.

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.
