Fix the following warning:

mpc8323erdb.c: In function 'mac_read_from_eeprom': mpc8323erdb.c:198:3: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] if (crc32(crc, buf, 24) == *(unsigned int *)&buf[24]) { ^

Size remains unchanged after and before fix:

text data bss dec hex filename 206977 18748 23344 249069 3cced ./u-boot

Note the fix is the crudest possible, but also least intrusive.
