While I'm fine with the change to pci_common_init_dev(), I am not so
sure about the removal of mvebu_pcie_scan_bus(). I vaguely remember
that we intentionally did not use the default function for a specific
reason. Of course, this was a long time ago, and I don't remember the
reason. I would have to take a bit of time to 1/ review the archives of
the discussion surrounding the pcie-mvebu driver, and 2/ test your
patch to validate it works fine on HW.

Thanks!

Thomas
