SPD has minor change from Rev 1.2 to 1.3. This patch enables Rev 1.3. The difference has ben examined and the code is compatible. Speed bins is not verified on hardware for CL7 at this moment.
This patch also enables SPD Rev 1.x where x is up to "F". According to SPD spec, the lower nibble is optionally used to determine which additinal bytes or attribute bits have been defined. Software can safely use defaults. However, the upper nibble should always be checked.
