When a memory bank is already registered, return an error code
instead of throwing a bug. This can happen if a board has registered
a memory bank and the same bank is then probed from the devicetree.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

Storing the size instead of the resource end in struct resource was
a mistake. 'size' ranges from 0 to UINT[32|64]_MAX + 1 which obviously
leads to problems. 'end' on the other hand will never exceed
UINT[32|64]_MAX. Also this way we can express a iomem region covering
the whole address space.

Thanks to a common memory handling barebox knows the sdram banks
and sizes, so we can add a common fixup functions for the nodes
in the devicetree.

On arm we have the concept of memory banks which can
be registered and iterated over. This is useful for
other architectures aswell, so add some generic infrastructure
for this.
