mb/prodrive/hermes: Get rid of variant structure

There's no need to use a variant structure here. Only one variant is
used, and revision-specific differences are handled at run-time, and
it's unlikely that another variant will ever exist.

Reorganize the mainboard code to get rid of the variant structure.
