Merge branch 'pci/header-cleanup-immutable' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git

The OpenRISC PCI support depends on the fixups done in the
pci/header-cleanup-immutable branch.  Also, there are OpenRISC
irqchip fixups in v5.19-rc6 that are needed to test the virt platform.

This merge creates a base for the OpenRISC PCI changes.
