x86/platform/UV: Move blade local processor ID to the per cpu info struct
Move references to blade local processor ID to the new per cpu info
structs. Create an access function that makes this move, and other
potential moves opaque to callers of this function. Define a flag
that indicates to callers in external GPL modules that this function
replaces any local definition. This allows calling source code to be
built for both pre-UV4 kernels as well as post-UV4 kernels.
