Many of the Gateworks Ventana boards have a PLX PCIe switch where GPIO
on the switch is used as the PERST# of the downstream ports. In the Linux
kernel there is a PCI fixup that asserts these properly when the upstream
port is enumerated.
The first patch in this serial adds a board_pci_fixup_dev function define
to allow hooking similarly to the kernel pci fixup functionality.
The second patch uses the board_pci_fixup_dev function to perform the
GPIO configuration on the switch for the downstream ports.
