iio: cros: Register FIFO callback after sensor is registered
Instead of registering callback to process sensor events right at
initialization time, wait for the sensor to be register in the iio
subsystem.
Events can come at probe time (in case the kernel rebooted abruptly
without switching the sensor off for instance), and be sent to IIO core
before the sensor is fully registered.
Fixes: aa984f1ba4a4 ("iio: cros_ec: Register to cros_ec_sensorhub when EC supports FIFO")
