drm/i915: Introduce intel_cpu_info.c for CPU IDs

Browse source 
Having similar naming convention in intel-family.h and intel_device_info.h
results in redefinition of a few platforms. Define CPU IDs in its own file
to avoid this.

v3: Move file out of gt directory, add kernel doc (Riana)
    Rephrase file description (Jani)
