Remove rmw_set(), rmw_clear(), clear_register(), rmw_set_fw(), and
rmw_clear_fw(). They're just one too many levels of abstraction for
register access, for very specific purposes.
clear_register() seems like a micro-optimization bypassing the write
when the register is already clear, but that trick has ceased to work
since commit 06b975d58f ("drm/i915: make intel_uncore_rmw() write
unconditionally"). Just clear the register in the most obvious way.

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.
