Subject: [PATCH v2] ARM: dts: Add pwm-fan node to the Odroid-U3 board

Add pwm-fan node to the Odroid-U3 board file to enable PWM control of the
cooling fan. In addition, add the "pwm" label to the pwm@...D0000 node
in the exynos4412.dtsi.

Signed-off-by: Kamil Debski <k.debski@...sung.com>

Changes since v1:
- added pwm label to the pwm@...D0000 node in exynos4.dtsi
- use the pwm label in the exynos4412-odroidu3.dts
- change order or properties in the pwn-fan node, to be sorted
  in alphabetical order
