This enables the Sparc to use <asm-generic/io.h> to fill in the missing (undefined) [read|write]sq I/O accessor functions. This is needed if Sparc[64] ever wants to uses CONFIG_REGMAP_MMIO which has been patches to use accelerated _noinc accessors such as readsq/writesq that Sparc64, while being a 64bit platform, as of now not yet provide. This comes with the requirement that everything the architecture already provides needs to be defined, rather than just being, say, static inline functions. Bite the bullet and just provide the definitions and make it work. Compile-tested on sparc32 and sparc64.

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.
