IIRC Maxime was against having chip names in here, as we would end up
updating this every time a new chip gets added.

Instead, what about using Allwinner's explanation? I.e. sun8i is a
chip with only Cortex-A7's, and sun9i is a chip with Cortex-A15's.
And just tell the user to say yes if they are not sure.
