Subject: [PATCH] brcm47xx: use DMZ LED as status indicator

On the Linksys WRT54GSv1, the Power LED flickers in the "off" state.
Indicate status using the DMZ LED if available, since it has solid "on" and
"off" states.

This change was tested on the WRT54GSv1, but may also affect other brcm47xx
devices.

Fixes FS#793.
