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.
