[PATCH v5 04/12] leds: cros_ec: Implement offloaded() trigger callback

"chromeos-auto" is a private hardware control trigger which always stays
in hardware control. Implement offloaded() callback with its return
value to be always true to reflect this.

I am aware of a pre-existing bug on probe, i.e., non-idempotent trigger
registration. Since the driver is very platform-specific and the
relevant platforms never have more than one such device, the bug is
never triggered on real devices. Therefore, fixing it is far beyond the
scope of the series.
