Sandybridge: Temporarily disable MRC cache finding code

This code is still using libfdt which was denied for inclusion
    in coreboot, so it won't compile as is.
    Without MRC cache, waking from suspend won't work, and cold boots are
    significantly slower (adds around 300-400ms per channel IIRC).
    A rework of this code is currently in the works, but will take a little bit
    more time (and should not hold back the mainboards being merged)
