[PATCH v1 1/6] ARM: dts: fix the correct pinctrl control for rk3036

[Caesar Wang]

The pinctrl gpio pull up/down is incorrect since the rk3036 SoCs
can't set the status in the internal.

We should keep the default status for enable the gpio status,
In fact, the pull_none is the disable the gpio pull up/down.
