This patch modifies the current Hip05/Hip06 PCIe host controller
driver to make it ECAM compliant. This is needed in preparation
for the ACPI based driver to allow both DT and ACPI drivers to
use the same BIOS (that configure the Designware iATUs).

Doesn't this break backwards compatibility?

I think you need to use a new compatible string in the firmware
if you change the register layout, and then change the driver
to support both the old and the new layout.
