[Arthur Heymans (Code Review)]

Hello Matthew Garrett, Aaron Durbin, Patrick Rudolph, Matt DeVillier, build bot (Jenkins), Patrick Georgi,

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

https://review.coreboot.org/c/coreboot/+/30432

to look at the new patch set (#17).

Change subject: drivers/smmstore: Fix some issues
......................................................................

drivers/smmstore: Fix some issues

This fixes the following:
- Fix smmstore_read_region to actually read stuff
- clean up the code a little
- Change the loglevel for non error messages to BIOS_DEBUG
- use an incoherent rdev to potentially speed up reading access

TESTED on google/wolf with out of tree patch to hook up smmstore to
sb/intel/lynxpoint.
