Stated another way, the Marvel PCI-E to PCI-E bridge config space has
a quirk that requires the window BARs to be aligned on their size and
sized to a power of 2.

The first requirement is already being handled by hooking through
ARM's 'align_resource' callback.

One avenue would be to have mvebu_pcie_align_resource return a struct
resource and manipulate the size as well. Assuming the PCI core will
accommodate that.
