lantiq: xrx200: rename nas0/ptm0 to dsl0

This change makes it possible to configure the wan/dsl ppp interface
settings independantly from the used TC-Layer (ATM/PTM).

Now you can move a device from an ADSL/ATM port to an VDSL/PTM port
without any configuration changes for example.

[use the dsl0 interface name for the default netdev trigger in 01_led,
add ip dependency]
