powerpc: Add missing NULL terminator to avoid boot panic on PPC40x

commit e6449c9b2d90c1bd9a5985bf05ddebfd1631cd6b upstream.

The missing NULL terminator can cause a panic on
PPC405 boards during boot:

  Linux/PowerPC load: console=ttyS0,115200 root=/dev/mtdblock1 rootfstype=squashfs,jffs2 noinitrd init=/etc/preinit
  Finalizing device tree... flat tree at 0x6a5160

  Kernel panic - not syncing: Attempted to kill the idle task!

The panic happens since commit 9597abe00c1bab2aedce6b49866bf6d1e81c9eed
(sections: fix section conflicts in arch/powerpc), however the root
cause of this is that the NULL terminator were not added in commit
a4f740cf33f7f6c164bbde3c0cdbcc77b0c4997c (of/flattree: Add of_flat_dt_match()
helper function).
