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.
