Draft: i2c/smbus_eeprom: Add feature bit to SPD data

Add the differential clock input feature bit to the generated SPD data. Most guests don't seem to care but pegasos2 firmware version 1.2 checks for this bit and stops with unsupported module type error if it's not present. Since this feature is likely present on real memory modules add it in the general code rather than patching the generated SPD data in pegasos2 board only.
