I'm not fond of the overly complicated names; and I think it should at
least be shortened to "db600c:...".

Tested this on my DB600c, seems to work, except the WiFi/BT triggers,
see comments below.

This should either be "phy0rx", "phy0tx", "phy0assoc" or "phy0radio". TX
does not seem to work, so this should be debugged; "assoc" is probably
the one that makes most sense.

This should be "hci0-power".
