[U-Boot] [PATCH] powerpc/eeprom: update MAX_NUM_PORTS to fix program failure

[Shengzhou Liu]

On some boards, the size of EEPROM is 128 Bytes instead of 256.
so we set default MAX_NUM_PORTS to 9 rather than previous 23 to
avoid the programming failure, we can define MAX_NUM_PORTS in
board-specific header file to overwrite the default value.
