Matt DeVillier 786ac14d48 drivers/option/cfr: Add optional override table for default values 
Add a mechanism for mainboards to override default values of CFR
objects defined in SoC or common code without duplicating object
metadata.

Mainboards can now declare a simple override table mapping option
names to new default values:

  const struct cfr_default_override mb_cfr_overrides[] = {
      CFR_OVERRIDE_BOOL("s0ix_enable", false),
      CFR_OVERRIDE_ENUM("pciexp_aspm", ASPM_DISABLE),
      CFR_OVERRIDE_END
  };

The CFR backend checks this table when writing options and uses the
override value if one exists. All other metadata (name, help text,
enum values, flags) comes from the original object.
