Add SPD support for onboard ThinkPad T480S RAM

Patchset 20 from:

https://review.coreboot.org/c/coreboot/+/83274/18..20

Updated to that. A bunch of changes I made locally have been
copied here, thus removed from lbmk.

The previous setup in lbmk was to have only the DIMM slot work,
on the ThinkPad T480S, without setting up SPD for the onboard RAM>

Mate Kukri reverse engineered the scheme by which the SPDs are
chosen at boot, based on the wiring of the board. This should
just about match the way Lenovo did it in their firmware.
