drm/i915: Introduce intel_cpu_info.c for CPU IDs
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)
