dt-bindings: leds: Convert gpio-leds to DT schema
Convert the gpio-leds binding to DT schema format. Drop the last example as the node name collides when built, and it doesn't add much value.

-LEDs connected to GPIO lines
-
-Required properties:
-- compatible : should be "gpio-leds".
-
-Each LED is represented as a sub-node of the gpio-leds device. Each
-node's name represents the name of the corresponding LED.
-
-LED sub-node properties:
-- gpios : Should specify the LED's GPIO, see "gpios property" in
- Documentation/devicetree/bindings/gpio/gpio.txt. Active low LEDs should be
- indicated using flags in the GPIO specifier.
-- function : (optional)
- see Documentation/devicetree/bindings/leds/common.txt
-- color : (optional)
- see Documentation/devicetree/bindings/leds/common.txt
-- label : (optional)
- see Documentation/devicetree/bindings/leds/common.txt (deprecated)
-- linux,default-trigger : (optional)
- see Documentation/devicetree/bindings/leds/common.txt
-- default-state: (optional) The initial state of the LED.
- see Documentation/devicetree/bindings/leds/common.txt
-- retain-state-suspended: (optional) The suspend state can be retained.Such
- as charge-led gpio.
-- retain-state-shutdown: (optional) Retain the state of the LED on shutdown.
- Useful in BMC systems, for example when the BMC is rebooted while the host
- remains up.
-- panic-indicator : (optional)
- see Documentation/devicetree/bindings/leds/common.txt
