[media] DVB: dib0700, add support for Nova-TD LEDs
Add an override of read_status to intercept lock status. This allows us to switch LEDs appropriately on and off with signal un/locked. The second phase is to override sleep to properly turn off both. This is a hackish way to achieve that. Thanks to Mike Krufky for his help.
