Hello build bot (Jenkins), Paul Menzel, Angel Pons,

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

to look at the new patch set (#4).

nb/intel/snb: Default to SPD info from devicetree for native raminit

This change adds a default mainboard_get_spd() that gets the SPD
addresses from a devicetree entry previously implemented for
MRC raminit.

This default is __weak until all boards have been migrated, to prevent
build breakage. At this time boards with onboard RAM and SPD data
in a file in CBFS will not be migrated.

TEST=Boot asus/p8x7x-series/p8z77-m to OS, RAM config logged during
native raminit did not change.
