[patch] move MAX_CPUS to cpu.h

[Jes Sorensen <jes@sgi.com>]

Hi,

I noticed that qemu-kvm.c hardcodes the array of struct vcpu_info
to 256, instead of using the MAX_CPUS #define. This patch corrects
this by moving the definition of MAX_CPUS to cpu.h from vl.c and
then fixes qemu-kvm.c

Cheers,
Jes

Move definition of MAX_CPUS from vl.c to architecture specific cpu.h
header file. Also change array of struct vcpu_info in qemu-kvm.c to
use MAX_CPUS instead of hardcoded value of 256.
