Add r8a779f0_eth_serdes_power_on() to initialize the hardware for each channel from the step 9 or later on the datasheet. In other words, the procedure from the step 1 to 8 is for all channel and it is needed once only. So, the .init() in any channel instance is called, this driver initializes the hardware from step 1 to 8. And then, .power_on() is called, this driver initializes the hardware from step 9 or later.

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.
