base-files: add more name source to get_dt_led helper function
Not all LED driver are using the label devicetree property for the led name. Add support for the TI/National Semiconductor LP55xx Led Drivers, which are using the chan-name property for the led name, as fallback. Signed-off-by: Mathias Kresin <dev@kresin.me>
