lantiq: reorganize 02_network board.d files

This reorganizes 02_network board.d files based on what's done for
ath79 and ramips: Instead of putting all settings into a single big
case, the interface/dsl/MAC address setup is put into separate
functions with a specific switch case for each of them. This makes
grouping of devices much easier and should be easier to read, too.
