PS5: 
Despite the discussion of the default behaviour, two general questions:
1. Will it be more reasonable if we check-flashrom-presence then if support, USE_LIBFLASHROM=1 else 0?
IMO always passing USE_LIBFLASHROM=0 is reasonable, but I would like to raise this question to see if it worth discussing.

2. We should also pass USD_LIBFLASHROM=0 in util/cbfstool/Makefile
