locomo: make locomo_bus_type constant and static

Browse Source 
Now that the driver core can properly handle constant struct bus_type,
move the locomo_bus_type variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.

It's also never used outside of arch/arm/common/locomo.c so make it
static and don't export it as no one is using it.
