Sorry if I have not been clear enough, but what I meant was that we
could probably create a 5v regulator in sunxi-common-regulators. It
will probably be useful for other boards in the same case, so we'd
better put it there, instead of redefining it everywhere (just like we
did for reg_vcc3v and reg_vcc3v3)
