Did you really mean for these both to map to the same speedbin?

Yes

There were more entries previously but the info was unclear and
different between BSPs..

For non-development SoCs it seems that "everything except FC_AC, FC_AF
should be speedbin 1", but what the values are for said "everything" are
not known, so that's an exercise left to the user..
