Hector Martin b10eb2d509 asm-generic/io.h: implement pci_remap_cfgspace using ioremap_np
Now that we have ioremap_np(), we can make pci_remap_cfgspace() default
to it, falling back to ioremap() on platforms where it is not available.

Remove the arm64 implementation, since that is now redundant. Future
cleanups should be able to do the same for other arches, and eventually
make the generic pci_remap_cfgspace() unconditional.

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.
