x86/platform/UV: Create per cpu info structs to replace per hub info structs
The major portion of the hub info is common to all cpus on that hub.
This is step one of moving the per cpu hub info to a per node hub info
struct. This patch creates the small per cpu info struct that will
contain only information specific to each CPU.
