Since commit a0fd361db8 ("PCI: dwc: Move "dbi", "dbi2", and
"addr_space" resource setup into common code"), the code
setting dbi_base when the config space is defined in 'ranges' property
instead of 'reg' is dead code as dbi_base is never NULL.
Rather than fix this, let's just drop the code. Using ranges has been
deprecated since 2014. The only platforms using this were exynos5440,
i.MX6 and Spear13xx. Exynos5440 is dead and has been removed. i.MX6 and
Spear13xx had PCIe support added just before this was deprecated and
were fixed within a kernel release or 2.

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.
