MIPS: PCI: Introduce CONFIG_PCI_DRIVERS_LEGACY
Introduce 2 Kconfig symbols, CONFIG_PCI_DRIVERS_GENERIC & CONFIG_PCI_DRIVERS_LEGACY, which indicate whether the system should be built to for PCI drivers using the MIPS-specific struct pci_controller API (hereafter "legacy" drivers) or more generic drivers using only functionality provided by the PCI core (hereafter "generic" drivers). The Kconfig entries are created such that platforms have to select CONFIG_PCI_DRIVERS_GENERIC if they wish to use it - that is, the default is CONFIG_PCI_DRIVERS_LEGACY so that existing platforms need no modification. The functions declared in pci.h are rearranged with those provided only by pci-legacy.c being guarded by an #ifdef CONFIG_PCI_DRIVERS_LEGACY to ensure they are only used in configurations where they are implemented.
