Add support to read MAC addresses from mac address multirecord. Check if multi record is found, then jump to mac address multirecord by comparing the record type field. If it matches mac address multirecord(0xD2), then copy mac addresses. Copy these read MAC address in xilinx_read_eeprom_fru so that they are updated to eth*addr in board_late_init_xilinx().
