There is a repeated pattern in multiple drivers where they want to switch the bandwidth between zero and some other value. This is happening often in the suspend/resume callbacks. Let's add helper functions to enable and disable the path, so that callers don't have to take care of remembering the bandwidth values and handle this in the framework instead. With this patch the users can call icc_disable() and icc_enable() to lower their bandwidth request to zero and then restore it back to it's previous value.

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.
