Move hardware configuration to governor's start/resume methods. This allows to re-initialize hardware counters and reconfigure cleanly if governor was stopped/paused. That is needed because we are not aware of all hardware changes that happened while governor was stopped and the paused state may get out of sync with reality, hence it's better to start with a clean slate after the pause. In a result there is no memory bandwidth starvation after resume from suspend-to-ram that results in display controller underflowing that happens on resume because of improper decision made by devfreq about the required memory frequency. This change also cleans up code a tad by moving hardware-configuration code into a single location.

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.
