Browse Source 
Based on public Intel 700 Series PCH datasheet, DOC 743835 rev 004.

The IDs of IoT chipset SKUs (ending with E) can only be found in "12th
Gen Intel® Core™ Processors Family (Formerly Known as Alder Lake -S)
for IoT Platforms External Design Specification (EDS) Addendum" DOC
634528 rev 2.7 (NDA).

TEST=Probe flash on Z790 chipset. Run the ich_descriptors_tool and
check the output is correct as expected.
