Revert of Try ARMv7 and NEON for Daisy. (patchset #1 id:1 of https://codereview.chromium.org/1054233002/)

Reason for revert:
whatever compiler we're using can't handle array subscripts for neon vectors

Original issue's description:
> Try ARMv7 and NEON for Daisy.
>
> I think Daisy's color order problems are in non-NEON ARM assembly.
> NEON might actually be fine.
