The old SD handling code was huge and could not handle all the details which showed up on R-Car Gen3 SoCs meanwhile. It is time to switch to another design. Have SDnH a separate clock, use the existing divider clocks and move the errata handling from the clock driver to the SDHI driver where it belongs. This patch removes the old SD handling code and switch to the new one. This updates the SDHI driver at the same time. Because the SDHI driver can only communicate with the clock driver via clk_set_rate(), I don't see an alternative to this flag-day-approach, so we cross subsystems here. The patch sadly looks messy for the CPG lib, but it is basically a huge chunk of code removed and smaller chunks added. It looks much better when you just view the resulting source file.

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.
