tree/: Convert flashchip probe func ptr to enumerate

Browse Source 
This forges the way for flashchips.c to be pure declarative
data and lookup functions for dispatch to be pure. This
means that the flashchips data could be extracted out to
be agnostic data of the flashrom code and algorithms.

TEST='R|W|E && --flash-name' on ARM, AMD & Intel DUT's.
