[systemd-devel] [PATCH v3 2/2] Add more firewire properties for sound, to be closer to USB and PCI

USB and PCI soundcards have a nice set of ID_* properties. It would
be handy for firewire soundcards to have the same.

Note that this removes the explicit setting of ID_ID in the firewire
conditional. Because we are now setting ID_SERIAL, ID_ID will come
from later in the file.
