ramips: Add Alpha ASL-26555 support.

This board uses a TrendChip SOC with its own RAM/Flash for ADSL support.
We know both SOCs are connected through ethernet and use some kind of protocol for UART communication, but due to the lack of GPL sources we couldn't get it to work. For this reason the network is configured only for LAN.

There are two versions (Chile 8MB and Spain 16MB).
