platform/chrome: cros_ec: Fix panic notifier registration
Initialize panic notifier to avoid the following lockdep warning:
INFO: trying to register non-static key.
The code is fine but needs lockdep annotation, or maybe
you didn't initialize this object before use?
turning off the locking correctness validator.
[...]
Hardware name: Samsung Exynos (Flattened Device Tree)
Workqueue: events_unbound async_run_entry_fn
unwind_backtrace from show_stack
[...]
blocking_notifier_chain_register from cros_ec_debugfs_probe
cros_ec_debugfs_probe from platform_probe
Fixes: d90fa2c64d59 ("platform/chrome: cros_ec: Poll EC log on EC panic")
