Hexagon's implementation of arch_atomic_cmpxchg() is identical to its implementation of arch_cmpxchg(). Have it define arch_atomic_cmpxchg() in terms of arch_cmpxchg(), matching what it does for arch_atomic_xchg() and arch_xchg(). At the same time, remove the kerneldoc comments for hexagon's arch_atomic_xchg() and arch_atomic_cmpxchg(). The arch_atomic_*() namespace is shared by all architectures and the API should be documented centrally, and the comments aren't all that helpful as-is. There should be no functional change as a result of this patch.

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.
