This is a preparation before adding the Msg-type outbound iATU mapping. The respective update will require two more arguments added to __dw_pcie_prog_outbound_atu(). That will make the already complicated function prototype even more hard to comprehend accepting _eight_ arguments. To prevent that and keep the code more-or-less readable, move all the outbound iATU-related arguments to a new config structure: struct dw_pcie_ob_atu_cfg, and pass a pointer to dw_pcie_prog_outbound_atu(). The structure should be locally defined and populated with the outbound iATU settings implied by the caller context. As a result of this change there is no longer need in having the two distinctive methods for the Host and Endpoint outbound iATU setups since the code can directly call the dw_pcie_prog_outbound_atu() method with the config structure populated, so drop dw_pcie_prog_ep_outbound_atu().

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.
