[media] firedtv: remove obsolete ieee1394 backend code
drivers/ieee1394/ has been removed in Linux 2.6.37. The corresponding backend code in firedtv is no longer built in now and can be deleted. Firedtv continues to work with drivers/firewire/. Also, fix a Kconfig menu comment: Removal of CONFIG_IEEE1394 made the "Supported FireWire (IEEE 1394) Adapters" comment disappear; bring it back with corrected dependency.
