In particular, the Arm FVP platforms use the host-generic driver. This conversion was straight-forward. I didn't convert the other ECAM drivers using host-common to modules, but am happy to do so if there's a strong desire to do so. In the process, I noticed that 'const' was being dropped from the match table .data pointer, so the first patch constifies struct pci_ecam_ops. I started trying to constify pci_ops too, but that became a never ending treewide rabbit hole. So I ended up with a cast when we assign pci_ops from pci_ecam_ops.
