The current setup of LM3692X_BOOST_CTRL uses flags from LM3692X_BRT_CTRL.
Use flags from LM3692X_BOOST_CTRL but leave the resulting register value
unchanged.

Instead use devm_regulator_get_optional since the regulator
is optional and check for errors.

The driver currently reports successful initialization on every failure
as long as it's able to power off the regulator. Don't check the return
value of regulator_disable to avoid that.

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.
