Subject: [PATCH 22/22] perf/x86/intel/rapl: rename internal variables in response to multi-die/pkg support

From: Len Brown <len.brown@...el.com>

Syntax update only -- no logical or functional change.

In response to the new multi-die/package changes, update variable names
to use the more generic "pmuid" terminology, instead of "pkgid",
as the pmu can refer to either packages or die.
