At least what we'd decided a year or two ago was to call _everything_
with an msm* prefix.  If marketing comes up with cute prefixes for
things, we would basically ignore them.  So, under that, it should be
an msm8074-dragonboard.  Admittedly, it might be a little confusing
with the name of the product having the apq in it, but as others have
pointed out, I think there is less confusing than not having a common
prefix on our MSM products.

At least so far, there are no chips where apq vs msm actually
distinguishes anything.  In fact, a simple "decoder ring" would point
out that the 'apq' usually corresponds with the second digit being a
zero.  It doesn't help that we've added an 'mpq' prefix as well.

I don't really see how to satisfy all of this other than qcom-apq*, or
just continue to use msm*.
