PCI: endpoint: pci-epf-test: Advertise dynamic inbound mapping support
The doorbell test requires the EPC driver to support dynamic inbound
mapping so the host can map the doorbell target address into a BAR
aperture.
Expose epc_features->dynamic_inbound_mapping via a new
CAP_DYNAMIC_INBOUND_MAPPING bit in the pci-epf-test capability register,
so the host-side pci_endpoint_test driver can detect missing support and
return -EOPNOTSUPP instead of running the test fruitlessly.
