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

[Caesar Wang]

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.
