Sascha,

coming back to this I am wondering if a full sync of linux' drivers/of
with barebox' drivers/of should be done. IMHO at least for the core
stuff (base/address/fdt) it makes sense, of_* can come later if
required.

I started merging already, and from what I can see we should just remove
the spinlocks and OF_DYNAMIC stuff (but leave of_node_get/_put as stubs)
