The SoC change must be separate from the board change.

Please leave a comment explaining what these GPIOs are
used for.
I checked these gpio setting, the gpio0 ~ gpio3 are for NFC eSE SPI,
gpio136 is for LPI Debug.

Use 0x0 consistently.
I will update this for using "0x0" instead of "0".

Totally unrelated change, fix the patch introducing it instead.
