[U-Boot] [PATCH] powerpc/c29xpcie: Getting DDR SPD image from 16-bit sub-address EEPROM

[Po Liu]

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.
