PCI: endpoint: Add pci_epf_assign_bar_space() API
Add pci_epf_assign_bar_space() API to allow setting any MMIO address as
the BAR memory space, such as an MSI message base address.
This API also conforms to the BAR base address and size alignment
restrictions enforced by the PCI spec r6.0, sec 7.5.1.2.1.
