PCI: endpoint: Add dynamic_inbound_mapping EPC feature
Introduce a new EPC feature bit (dynamic_inbound_mapping) that indicates
whether an Endpoint Controller can update the inbound address
translation for a BAR without requiring the EPF driver to clear/reset
the BAR first.
Endpoint Function drivers (e.g. vNTB) can use this information to decide
whether it really is safe to call pci_epc_set_bar() multiple times to
update inbound mappings for the BAR.
