powercap/intel_rapl: Support multi-die/package
RAPL "package" domains are actually implemented in hardware per-die. Thus, the new multi-die/package systems have mulitple domains within each physical package. Update the intel_rapl driver to be "die aware" -- exporting multiple domains within a single package, when present. No change on single die/package systems.
