libie: add PCI device initialization helpers to libie

Browse source 
idpf and ixd drivers serve different PCI functions on the same device,
therefore their PCI configuration flow is very similar.

Add support functions for idpf and ixd to configure PCI functionality and
access MMIO space. Add a mapping list which can be traversed by a driver,
e.g. to pass certain I/O mappings to the auxbus devices. Such list is also
traversed by the libie_pci_get_mmio_addr() helper, which allows for easier
memory access.
