The constants EXT_CFG_DATA and EXT_CFG_INDEX vary by SoC, where one of the map_bus methods used these constants, and the other used a different set of constants. Thankfully, there was no problem because the SoCs that used the latter map_bus method all had the same register constants. Thus, remove redundant constants and adjust the code to use the correct constants accordingly. While at it, update the value of EXT_CFG_DATA to use the 4k-page based configuration space access system, which is what the second map_bus method was already using.

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.
