Switch to using generic LED support for composing LED class
device name.
At this occassion remove initialization of struct led_classdev's
dev->of_node property in the driver, since now it will be taken from
fwnode assigned to struct led_init_data and passed to the new
devm_led_classdev_register_ext() API.

syncs need to be disabled.
The LM36923 has 3 LED syncs.
