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

* From v2 [2]:
  - Fixed the Xilinx driver, thanks to Bharat for testing it
  - Dropped the no_msi attribute, and solely rely on msi_domain, which
    has the same effect for the only platform that was using it.
  - Fixed compilation on architectures that do not select the generic
    MSI support

* 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.
