Add byte-swapping versions of __raw_writeq() and __raw_rm_writeq().
This allows us to avoid sparse warnings caused by passing __be64 to
__raw_writeq(), which takes unsigned long:
arch/powerpc/platforms/powernv/pci-ioda.c:1981:38:
warning: incorrect type in argument 1 (different base types)
expected unsigned long [unsigned] v
got restricted __be64 [usertype] <noident>
It's also generally preferable to use a byte-swapping accessor rather
than doing it by hand in the code, which is more bug prone.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
