Greetings, This adds a cputable entry for 750CXe DD2.4, as found in the GameCube from Nintendo. To be correctly enumerated, however, the table has to be slightly re-ordered first. Details within. Thanks. Arthur

"745/755" (pvr_value:0x00083000) is a catch-all entry. Since arch/ppc/kernel/misc.S:identify_cpu() returns on first match, move this lower in the table so 750CXe DD2.4 (pvr_value:0x00083214) may be correctly enumerated.
