[PATCH 7/7] powerpc/word-at-a-time: Instrument load_unaligned_zeropad()

[Bill Wendling]

Convert powerpc to the arch_load_unaligned_zeropad() /
load_unaligned_zeropad() split introduced for x86 earlier in this
series, so KASAN/KCSAN also see reads through load_unaligned_zeropad()
on this architecture.
