lib: lz4: cleanup unaligned access efficiency detection

rsalvaterra · gregkh · commit dea5c24a1404 · 2016-04-13T09:22:49.000-07:00
These identifiers are bogus. The interested architectures should define
HAVE_EFFICIENT_UNALIGNED_ACCESS whenever relevant to do so. If this
isn't true for some arch, it should be fixed in the arch definition.
