Eh... Well this implementation is better. I had the idea of adding
support on the uclass level but I preferred to limit it only to GPIO.

Think this would match how it's done in upstream linux kernel so I think
mine should be ignored and this taken (for sw blink).

Should not change a thing for the series since all the bits were using
generic LED functions.
