cpu/intel/model_206ax: Use parallel MP init This patch adds a few southbridge calls needed for parallel MP init. Moves the smm_relocate() function to smm/gen1/smi.h, since that is where this function is defined now. Tested on Thinkpad X220, shaves off ~30ms on a 2 core, 4 threads CPU.

Create i945-ivy smm tseg init based on ivy code. CPU-side logic is unchanged for this range of CPUs as long as all of them use TSEG (or ASEG, just needs to be consistent). So uplift 206ax code while extracting southbridge and APIC code into separate functions.

cpu/intel/smm: Use CONFIG_SMM_TSEG_SIZE An epic battle to fix Nehalem finally ended when we found an odd mask set in SMRR. This was caused by a wrong calculation of TSEG size. It was assumed that TSEG spans the whole space between TSEG base and GTT. This is wrong as TSEG base might have been aligned down. TEST: On X201, copied 1GiB from usb key to sd-card and verified.

nb/intel/gm45: Use common code for SMM in TSEG This makes i82801ix use the common smm southbridge code to set up smm relocation and smi handler setup. This is needed in this change for the the smm relocation code relies on some southbridge functions provided in the common code. Some of the old code is kept for the Q35 qemu target. This also caches the TSEG region and therefore increases MTRR usage a little in some cases. Currently SMRR msr's are not set on model_1067x and model_6fx since this needs the MSRR enable bit and lock set in IA32_FEATURE_CONTROL. This will be handled properly in the subsequent parallel mp init patchset. Tested on Thinkpad X200: boots and going to and resuming from S3 still works fine.

cpu/intel/smm/gen1: Add pineview to the check for alt SMRR MSR's Intel pineview has the same alternative SMRR MSR and IA32_FEATURE_CONTROL enable bit as core2 CPUs so properly check for that before enabling this feature. This also exposes a function to fetch whether alternative SMRR MSR's ought to be used.
