Change in flashrom[master]: ich_descriptors.c: Ensure unsigned types >=0 on to prevent underflow

It probably means that Intel initially thought that having 12 regions in the IFD would be more than enough for any future needs. Later, they realized that they needed more regions, so they added a new set of bitfields to have more regions. I imagine they preserved the field position for the original 12 regions for backwards compatibility purposes.
