Use address mask in probe_jedec

Browse Source 
This allows us to have one common probe_jedec function instead of half a
dozen wrappers. The trick here is to have FEATURE_ADDR_FULL==0 and thus
default to unmasked addresses. That way, we only have to annotate chips
which need small address masks.

Corresponding to flashrom svn r840.
