This commit introduces a bus resource abstraction. A bus resource
encapsulates bus specific information and semantics. Along with
abstracting away bus specific details and providing an overall
smoother interface, this additionally provides flexibility, access
control and security by keeping track of permissions and allowing
things to be turned on or off.

Uses recursive bus/bridge scanning, skips nonexistent devices, and only
scans for multiple functions on multifunction devices. This may result
in PCI scanning being up to 100x as fast.

This commit gets rid of pci_map_bar() as some devices have their
base address spanning mulitple BARs. This change also exposes PCI
bar size logic through pci_bar_size()
