Since there are platforms which have non-compliant ECAM space we need to
override these accessors prior to PCI buses enumeration. In order to do
that we call pci_mcfg_match_quirks() to retrieve custom
pci_config_window structure. If no correlated quirk on list, use
fully ECAM compliant generic PCI config accessors.
