Change in ...coreboot[master]: nb/intel/gm45: Use a common romstage

[Arthur Heymans (Code Review)]

Hello Alexander Couzens, Patrick Rudolph, Angel Pons, build bot (Jenkins), Patrick Georgi, Martin Roth,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/31190

to look at the new patch set (#3).

nb/intel/gm45: Use a common romstage

This moves a lot of the common romstage boilerplate code to a common
location, while adding a few mainboard specific hooks.

Another difference is that the settings for enable_igd and enable_peg
are now based on the static devicetree settings.
