ichspi: Add support for Meteor Lake

This patch adds Meteor Lake support into flashrom.

Additionally, utilize CSSO (CPU Soft Strap Offset) to uniquely detect
the chipset when the CSSL (CPU Soft Strap Length) field default value
(0x03) on Meteor Lake is the same as Elkhart Lake.

BUG=b:224325352
TEST=Flashrom is able to detect MTL SPI DID and show chipset name as below:
> flashrom --flash-name
....
Found chipset "Intel Meteor Lake-P/M".
....

> flashrom - internal --ifd -i fd -i bios -r /tmp/bios.rom
....
Reading ich_descriptor... done.
Assuming chipset 'Meteor Lake'.
Using regions: "bios", "fd".
Reading flash... done.
SUCCESS
