Allwinner H6 SoC has multiplier N range between 1 and 254. Since parent
rate is 24MHz, intermediate result when calculating final rate easily
overflows 32 bit variable.
Because of that, introduce function for calculating clock rate which
uses 64 bit variable for intermediate result.

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.
