ARM: dts: add cm36651 light/proximity sensor node for exynos4412-trats2

Browse Source 
Exynos4412-trats2 board have light/proximity sensor.
This patch add cm36651 light/ proximity sensor node for exynos4412.
cm36651 is required properties as below.
- Use i2c-gpio for cm36651 sensor.
- Use fixed regulator for the IR LED.
  It is a part of the cm36651 for proximity detection.
- cm36651 is i2c device driver so need to use i2c-gpio driver.
