[PATCH 00/10] Designware PCIe host fixes

[Bernhard Beschow <shentey@gmail.com>]

This series fixes the Designware PCIe host to work with cards other than
virio-net-pci, e.g. e1000. It was tested on the imx8mp-evk machine.

The series is structured as follows: The first part refactors the device
model to create memory regions for inbound/outbound PCI mappings on demand
rather than upfront since this approach doesn't scale for adding I/O space
support. The second part consists of fixing the memory mapping by adding I/O
space support and fixing default inbound viewport mapping. The third part
concludes the series by implementing device reset and cleaning up the imx8mp SoC
implementation.

Testing done:
* Boot imx8mp-evk machine with Buildroot while having an e1000 card attached.
Observe that it gets an IP address via DHCP and allows for downloading an HTML
file via HTTP.
