This reverts commit 3c5b006f3e.
gadget_is_{super|dual}speed() API check UDC controller capitblity. It
should pass down highest speed endpoint descriptor to UDC controller. So
UDC controller driver can reserve enough resource at check_config(),
especially mult and maxburst. So UDC driver (such as cdns3) can know need
at least (mult + 1) * (maxburst + 1) * wMaxPacketSize internal memory for
this uvc functions.

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.
