Support new nvidia,fixed-parent-rate device-tree property which instructs I2S that board wants parent clock rate to stay at a fixed rate. This allows to play audio over S/PDIF and I2S simultaneously. The root of the problem is that audio components on Tegra share the same audio PLL, and thus, only a subset of rates can be supported if we want to play audio simultaneously. Filter out audio rates that don't match parent clock rate if device-tree has the nvidia,fixed-parent-rate property.

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.
