At present pack() calls fdt_pack() which may well reduce the size of the
device-tree data. However this does not currently update the size of the
bytearray to take account of any reduction. This means that there may be
unused data at the end of the bytearray and any users of as_bytearray()
will see this extra data.
Fix this by resizing the bytearray after packing.
