[Angel Pons (Code Review)]

Hello Patrick Rudolph, Felix Held, build bot (Jenkins),

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

https://review.coreboot.org/c/coreboot/+/38036

to look at the new patch set (#6).

Change subject: nb/intel/sandybridge: Add a bunch of MCHBAR defines
......................................................................

nb/intel/sandybridge: Add a bunch of MCHBAR defines

While we are at it, also:
- Rename related variables to match the register names.
- Update some comments to better reflect what some registers are about.
- Add various FIXME comments on registers that seem to be used wrongly.

With BUILD_TIMELESS=1, this commit does not change the coreboot build of:
- Asus P8H61-M with native raminit.
- Lenovo Thinkpad X230 with native raminit.
- Lenovo Thinkpad X220 with MRC raminit.
