powerpc: Add missing NULL terminator to avoid boot panic on PPC40x
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
bootconsole [udbg0] enabled
Page fault in user mode with in_atomic() = 1 mm = (null)
NIP = c0275f50 MSR = fffffffe
Oops: Weird page fault, sig: 11 [#1]

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).
