Add a warning message when the selected PHY speed is less than supported minimum PHY speed given in the hsfreq table[1]. For raspberry pi camera capture on Kingfisher board with resolution 640x480, the calculated PHY speed is 48 mbps which is less than the minimum PHY speed 80 Mbps from the table[1]. But in this cases capture is successful.

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.
