board: freescale: p2041rdb: use correct EEPROM address length

These boards, according to the schematic and per the board I own, use an
M24256-BWDW6TP I2C EEPROM which requires two address bytes.

This fixes the 'mac' command which is used to program, among other
things, the MAC addresses for the ethernet interfaces on the board.
