smbus: Add a helper to generate SPD EEPROM data
There are several boards with SPD EEPROMs that are now using
duplicated or slightly different hard coded data. Add a helper to
generate SPD data for a memory module of given type and size that
could be used by these boards (either as is or with further changes if
needed) which should help cleaning this up and avoid further duplication.
