UBUNTU: SAUCE: Bluetooth: Use host bridge subsystem IDs to identify Edge Gateways

BugLink: https://launchpad.net/bugs/1512999

Since DMI IDs may be different between models while subsystem IDs of
host bridge will stay the same, use pci_get_subsys() instead of
dmi_match() to identify Edge Gateways.
