soc/intel/common: Consistently use smbus 7-bit address log format

The "No memory dimm at address" line in get_spd_sn and get_spd fucntion
have different format of SPD address.

get_spd_sn shows a 8-bit address format but get_spd shows a 7-bit
address format when there is no DIMM connected. It can be confusing
when debugging.
