If you think enumerating all variants is worthwhile, you should
probably be adding normal Dual (Quad, but with only 2 cores) as well.

I don't think that's helpful, you would need to at least also print
"Dual" to make it correct. The Solo is just a fused down version of the
DualLite, just as the Dual is a fused down version of the Quad.
Quad/DualLite refers to the two different die versions of the chip.

Perhaps we need to print Dual as well.
ATM "cat /proc/cpuinfo" (and everything using it) prints "Freescale
i.MX6 Quad/DualLite (Device Tree)" on Solo and this is, at best,
misleading: making people wonder what CPU do they really have.
