Add "make gen" target to regenerate em100pro_chips.h
This downloads the Windows release from dediprog.com and extracts
the per-chip data into em100pro_chips.h. It can be used to refresh
the list when new chip types are added upstream.
"make gen" will be invoked automatically if em100pro_chips.h is
somehow absent, but it will not be invoked during a normal build from
git sources.
