PCI: Add standard PCI Config Address macros

Browse source

Lot of PCI and PCIe controllers are using standard Config Address for PCI
Configuration Mechanism #1 (as defined in PCI Local Bus Specification) or
its extended version.

So introduce new macros PCI_CONF1_ADDRESS() and PCI_CONF1_EXT_ADDRESS() in
include file drivers/pci/pci.h which can be suitable for PCI and PCIe
controllers which uses this type of access to PCI config space.
