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.

The LM36922 has one output but can sync current to 2 LED
strings. The user may only use one sync so the other
syncs need to be disabled.
The LM36923 has 3 LED syncs.

Update the code to use the fwnode calls as opposed
to ARM DT node api's.
This allows the device to be used with either DT
configurations or ACPI definitions.
