Make read_ich_descriptors_from_dump() available in flashrom
I didn't really know what I was doing and hope removing the #ifdefs doesn't have negative side effects.
The idea is to make the functions generally available for external flashing (e.g. you might want to flash an Intel machine using an ARM device as programmer).
Beware of big endian trouble, I guess. :-P
