zynqmp_clk_divider_round_rate() returns actual divider value after calculating from parent rate and desired rate, even though that rate is not supported by single divider of hardware. It is also possible that such divisor value can be achieved through 2 different dividers. As, Linux tries to set such divisor value(out of range) in single divider set divider is getting failed. Fix the same by computing best possible combination of two divisors which provides more accurate clock rate.

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.
