[PATCH 1/2] perf/x86/intel/pt: Add format strings for PTWRITE and power event tracing

Commit 8ee83b2ab3 ("perf/x86/intel/pt: Add support for PTWRITE and power
event tracing") forgot to add format strings to the PT driver. So one
could enable these features by setting corresponding bits in the event
config, but not by their mnemonic names.

This patch adds the format strings.
