rtc: cros-ec: Only warn once in .remove() about notifier_chain problems

Browse source 
When a remove platform device callback returns an error code, the driver
core emits an error message ("remove callback returned a non-zero value.
This will be ignored.\n") and still removes the device. As the driver
already emits a more specific error message, return 0 to suppress the
core's error message.

This is a preparation for making platform remove callbacks return void.
