platform/x86: intel_telemetry: Add debugfs entry for S0ix residency

2017-07-05T18:26:35+00:00

This adds a debugfs consumer for the exported kernel API
intel_pmc_read_s0ix_residency. This debugfs entry reads S0ix residency
directly from the PMC hardware counters.

TEST:
- echo freeze > /sys/power/state
- Wake the system, read the S0ix residency i.e.
  cat /sys/kernel/debug/telemetry/s0ix_residency_usec

platform/x86: intel_telemetry_debugfs: fix oops when load/unload module

2017-07-05T18:24:41+00:00

This fixes an oops found while testing load/unload of the
intel_telemetry_debugfs module. module_init uses register_pm_notifier
for PM callbacks, but unregister_pm_notifier was missing from
module_exit.
