PCI: faraday: Convert IRQ masking to raw PCI config accessors
Current ftpci100 driver host bridge controller driver requires struct pci_bus to be created in order to mask and clear IRQs using standard PCI bus config accessors. This struct pci_bus dependency is fictitious and burdens the driver with unneeded constraints (eg to use separate APIs to create and scan the root bus). Add PCI raw config space accessors to PCIe ftpci100 driver and remove the fictitious struct pci_bus dependency.
