x86: make amd quad core 8 socket system not be clustered_box, #2
quad core 8 socket system will have apic id lifting.the apic id range could be [4, 0x23]. and apic_is_clustered_box will think that need to three clusters and that is large than 2. So it is treated as clustered_box. and will get Marking TSC unstable due to TSCs unsynchronized even the CPUs have X86_FEATURE_CONSTANT_TSC set. this patch will check if the cpu is from AMD.
