slippy/falco/peppy: Fix SPD GPIO initialization.

SPD GPIOs were being read prior to initialization in romstage_common. To
fix, pass the copy_spd function to romstage_common, to be called at the
appropriate time (after PCH init, before DRAM init).

BUG=chrome-os-partner:20162.
TEST=Manual. Test on peppy board with non-zero SPD GPIOs, verify correct
SPD is selected.
