[pci] Add support for the Enhanced Configuration Access Mechanism (ECAM)
The ACPI MCFG table describes a direct mapping of PCI configuration
space into MMIO space. This mapping allows access to extended
configuration space (up to 4096 bytes) and also provides for the
existence of multiple host bridges.
Add support for the ECAM mechanism described by the ACPI MCFG table,
as a selectable PCI I/O API alongside the existing PCI BIOS and Type 1
mechanisms.
