To solve this, we need to change the pci-mvebu driver and the core code first to let the driver override pcibios_align_resource() through an operation in struct pci_host_bridge. The other remaining use of dev->sysdata is the ARM pcibios_msi_controller() function that overrides the generic implementation. To solve this, we need to change the five remaining drivers that set hw_pci->msi_ctrl to use the new generic method, and remove the ARM specific implementation.
