[PATCH] x86: Fix CONFIG_NUMA help message

[Andi Kleen]

Noticed recently while looking at this file. The x86 NUMA Kconfig help
entry is not quite correct.

- Core i7 systems are always non NUMA. Refer to multi socket Nehalems instead.
- Replace outdated EM64T term with Intel 64

Why Xeon 75xx and not 55xx ?
