Currently, there is only one EEPROM on c29xpcie board which isAT24C1024. We program the SPD data at beginning of the AT24C1024.But the AT24C1024 has a 16-bit sub-address mode. This patch is tomake it work when getting SPD in a 16-bit sub-address EEPROM.

Please fix the compiling warning. You need to include i2c.h, per internal review.
