According to the datasheet, the VSC73xx family's maximum internal MDIO bus speed is 20 MHz. It also allows disabling the preamble. This commit sets the MDIO clock prescaler to the minimum value and disables the preamble to speed up MDIO operations. It doesn't affect the external bus because it's configured in a different subblock.

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.
