Convert open coded RMW accesses for LNKCTL2 to use pcie_capability_clear_and_set_word() which makes its easier to understand what the code tries to do. In addition, this futureproofs the code. LNKCTL2 is not really owned by any driver because it is a collection of control bits that PCI core might need to touch. RMW accessors already have support for proper locking for a selected set of registers to avoid losing concurrent updates (LNKCTL2 is not yet among the registers that need protection but likely will be in the future).

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 reStructuredText 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.
