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