ichspi: Add Intel Meteor Lake SoC

Hardware looks the same as C740 series / Emmitsburg. The descriptor
is somewhere between the latter and latest desktop platforms.

Output of `ich_descriptors_tool' with an image from Google/Rex looks
reasonable.

Tested probing and reading on a Lenovo L16 ThinkPad.

Documents used:
  * Intel® Core™ Ultra Processor Datasheet, Volumes 1 and 2
  * Meteor Lake/Arrow Lake-U / H Client Platform
