Browse Source 
TEST=Flashrom is able to detect WCL SPI DID and show chipset name as
below:

> flashrom --flash-name
....
Found chipset "Intel Wildcat Lake".
....
> flashrom -p internal --ifd -i fd -i bios -r /tmp/bios.rom
....
Found chipset "Intel Wildcat Lake".
Reading ich_descriptor... done.
Using regions: "bios", "fd".
Reading flash... done.
SUCCESS
