[PATCH 2/6] led-uclass: honour ->label field populated by driver's own .bind

[Rasmus Villemoes]

If the driver's own .bind method has populated uc_plat->label, don't
override that. This is necessary for an upcoming driver for ti,lp5562,
where the DT binding unfortunately says to use "chan-name" and not
"label".
