[PATCH v2 00/16] PCI: dwc: Another round of clean-ups

Here's another batch of DWC PCI host refactoring. This series primarily
moves more of the MSI, link up, and resource handling to the core
code. Beyond a couple of minor fixes, new in this version is runtime
detection of iATU regions instead of using DT properties.

No doubt I've probably broken something. Please test. I've run this thru
kernelci and checked boards with DWC PCI which currently is just
Layerscape boards (hint: add boards and/or enable PCI). A git branch is
here[1].

This is dependent on "PCI: dwc: Restore ATU memory resource setup to use
last entry" which will be in v5.10-rc3.
