The formula to generate the desired bus speeds has changed a little over time. Implement the new formula and allow drivers to opt-in by changing to this new config set. Ensure in probe that we don't divide by zero. The returned values on a R-Car H2 (r8a7790/Lager board) match the suggested values in the datasheet.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
