Some of the Primary Subsystem events differ on Gemini Lake but the IOSS
events remain same. This patch adds the updated PSS event table to enable
Telemetry driver on Gemini Lake.

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

There are bunch of "goto out;" paths where we don't set the error code.

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.
