Subject: [RFC PATCH v4 4/5] ARM64/PCI: Start using quirks handling for ACPI based PCI host controller

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.
