Instrumented cpuinfo to read the populated cpu info data from cpuid.info file during initialization. Consumers of the library or OEMs can trigger a oneshot service - cpuinfo-svc - during device boot to link libcpuinfo and dump all cpu info related to processor, model, arch and isa capabilities into cpuid.info file. This arrangement will limit cpuid() intrinsic calls (which causes VM-Exit events) to only once during init of libcpuinfo at boot by cpuinfo-svc.
