arm/mgcoge3un: check dip_switch at startup

Browse source 
Similar to kmcoge5un we need to check the dip switch at startup
connected to the kirkwood at MPP43. If it's set we need to set the
actual_bank to zero to boot from SW bank zero. Additional to kmcoge5un
we need to check also the pin in misc_init to decide wether we wait for
the ne to start or not. If the dip_switch is set we don't wait and
continue immediately.
