This commit adds sysfs support for ksz9477 register acccess in
userspace. Although access is possible through the use of regmap it
showed to be uncomfortable to work with whole register dumps and also
or security reasons write access is prohibited by deault.
Do a 16-bit read access:
echo 16 0x040C > ksz_read
A 32-bit wirte access:
echo 32 0x0120 0x0115 > ksz_write
Results will be logged in the kernel buffer.

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.
