Declutter the *_fbc_activate() functions by pulling all the control register value computations into helpers. I left the enable bit in *_fbc_activate() in the hopes of maybe using the helpers in the *_fbc_deactivate() paths as well instead of the current rmw approach. That won't be possible at least quite yet since we clobber the fbc->params before deactivating FBC so we could end up changing some of the values live, which given FBC's lack of/poor double buffering would likely not go so well.

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.
