6a436c9182 dm: led: Tidy up SPL options for the led and led-gpio 
At present SPL does not have its own option. But these features can
increase SPL code size. Adjust the Kconfig and Makefile so that
separate a SPL option can be selected.

5917112c9e dm: Add support for LEDs 
Add a simple uclass for LEDs, so that these can be controlled by the device
tree and activated when needed. LEDs are referred to by their label.

This implementation requires a driver for each type of LED (e.g GPIO, I2C).
