This is a respin of the series described at [1].

* From v1:
  - Extracted the changes dealing with the MSI capture address
    for rcar and xilinx and moved them to separate patches
  - Changed the rcar code to cope with c4e0fec2f7ee ("PCI: rcar: Always
    allocate MSI addresses in 32bit space")
  - Fixed rcar resume code
  - Reworked commit messages
  - Rebased onto v5.12-rc4
  - Collected Acks, and TBs, with thanks.
