[PATCH] Kconfig: use range for NR_CPUS

From: Adrian Bunk <bunk@fs.tum.de>

The 2.6 Kconfig language allows to set the range for integer questions.

The patch below adds a range line on all architectures that have a
NR_CPUS question except ia64.

The help text on ia64 didn't suggest any values. Could someone tell the 
correct values for ia64 (and if it's only a minimum value of 2)?
