[RFC] nb/intel/sandybridge: Pre-render constants in MRC pei_data

Portions of MRC raminit code only serves to enter fixed constants
into pei_data structure for MRC consumption.

Since the constants are all to the front of the structure, set up a
truncated copy for compiler to render at build time. Chipset code then
uses it as a base to initialize the (in-CAR) structure and fill out the
rest at runtime.

TEST=No regression observed when booting on asus/p8z77-m.
