[PATCH 3.16 327/366] word-at-a-time.h: fix some Kbuild files

[Ben Hutchings]

3.16.60-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Chris Metcalf <cmetcalf@xxxxxxxxxx>

commit 19c22f3a29fa8669c477f20a65f6c7c27108972a upstream.

arch/tile added word-at-a-time.h after the patch that added generic-y
entries; the generic-y entry is now stale.

arch/h8300 is newer than the generic-y patch for word-at-a-time.h,
and needs a generic-y entry.

arch/powerpc seems to have gotten a generic-y entry by mistake in
the first patch; this change removes it.

[bwh: Backported to 3.16:
 - Drop change in arch/h8300, which doesn't exist here
 - Drop change in arch/tile, which is still using the generic implementation]
