[PATCH v2 2/2] ARM: dts: rockchip: Add the OTP gpio pinctrl

Add the "init" pinctrl as the OTP gpio state.
We need the OTP pin is gpio state before resetting the TSADC controller,
since the tshut polarity will generate a high signal.

"init" pinctrl property is defined by Doug's Patch[0].

Changes in v2:
  - Add some commits for more obvious in PATCH[2/2]

Changes in v1:
  - As the Doug comments, drop the thermal driver patchs since
    we can with pinctrl changing to work.
  - As the Doug's patch to add the 'init' property.
