[PATCH V4 06/15] ARM: dts: imx6q-dhcom: Add keys and leds to the PDK2 board

[Christoph Niedermaier]

On the PDK2 there are 4 keys and 4 leds. DHCOM GPIOs are
used for that, but one led isn't useable, because the GPIO
is already used as touch interrupt.

V2: - Rebase on Shawn Guos branch for-next
V3: - Fix typo in commit message
    - Replace the property label with the
      properties color and function
V4: - Include dt-bindings/leds/common.h file
