In order to support mainboards that do not store DRAM part number in
the traditional way i.e. within the CBFS SPD for soldered memory, this
change provides a runtime callback to allow mainboards to provide DRAM
part number from a custom location e.g. external EEPROM on volteer /
dedede.
For other boards it should be a NOP since the weak implementation of
mainboard_get_dram_part_num does nothing.
