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.
