mvebu: LS421DE: add linkstation poweroff driver

Browse Source 
Compile the Linkstation poweroff module for the Buffalo LS421DE.
Without this driver the device remains forever halted if a power off
command is executed.

The driver will also allow to use the WoL feature, which wasn't availabe
in the stock firmware.
