Replace the UART frequency table 'root_freq[]' with logic around clk_round_rate() so that SoC details like the available clk frequencies can change and this driver still works. This reduces tight coupling between this UART driver and the SoC clk driver because we no longer have to update the 'root_freq[]' array for new SoCs. Instead the driver determines the available frequencies at runtime.

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.
