The DesignWare EP core has supported updating the inbound iATU mapping

called again without a prior pci_epc_clear_bar()) since
commit 4284c88fff0e ("PCI: designware-ep: Allow pci_epc_set_bar() update
inbound map address").

Now that the EPC layer exposes this capability via the
dynamic_inbound_mapping feature bit, set the bit centrally in the
DesignWare EP layer so that all DWC-based EP glue drivers report it
consistently, without duplicating the same flag in each individual
driver.

No functional change intended. This only advertises existing behavior to
EPF drivers.
