[PATCH 3/3] powerpc/32: Convert patch_instruction() to patch_uint()

These changes are for patch_instruction() uses on data. Unlike ppc64
these should not be incorrect as-is, but using the patch_uint() alias
better reflects what kind of data being patched and allows for
benchmarking the effect of different patch_* implementations (e.g.,
skipping instruction flushing when patching data).
