leds: rgb: qcom-lpg: Use fwnode APIs for LED parsing

Convert LED and channel parsing in lpg_add_led() and
lpg_parse_channel() from DT-specific helpers to the fwnode API.
The probe loop now uses device_for_each_child_node_scoped(),
dropping explicit node lifetime handling.

Behaviour is unchanged for device tree: fwnode_get_child_node_count()
and both child iteration helpers skip unavailable children on OF,
and the fwnode handle is passed straight to LED registration.

cdev->default_trigger is only assigned when
fwnode_property_read_string() succeeds, so an absent
linux,default-trigger property no longer yields an uninitialized
pointer.
