Richard Zhu 81d1d214e1 PCI: imx6: Identify controller via 'linux,pci-domain', not address
Instead of testing the controller register address to distinguish
controller 1 from controller 0 on i.MX8MQ platforms, use the PCI domain
number, which comes from the devicetree 'linux,pci-domain' property.

All relevant devicetrees should already supply 'linux,pci-domain', which
was added by c0b70f05c8 ("arm64: dts: imx8mq: use_dt_domains for pci
node").

Instead of being set directly in imx_pcie_probe(), pci->dbi_base will be
set by the DWC core in dw_pcie_get_resources().

No functional changes intended.

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.
