98b7d04574 soc/common/smbus: Support reading SPD5 hubs for DDR5
DDR5 uses a Serial Presence Detect (SPD) with hub function
(SPD5 hub device) to store the SPD data. The SPD5 hub has 1024 bytes of
EEPROM (`CONFIG_DIMM_SPD_SIZE=1024`).

Tested on Clevo V560TU (system76/darp10) with 2x Crucial CT16G48C40S5
DIMMs.
