ARM: dts: imx6q-dhcom: Add gpios pinctrl for i2c bus recovery

[ Upstream commit ddc873cd3c0af4faad6a00bffda21c3f775126dd ]

The i2c bus can freeze at the end of transaction so the bus can no longer work.
This scenario is improved by adding scl/sda gpios definitions to implement the
i2c bus recovery mechanism.
