ARM: dts: imx6*-apalis/-colibri: mark I2C recovery GPIOs as open drain
Since commit d2d0ad2aec4a ("i2c: imx: use open drain for recovery GPIO") GPIO lib expects this GPIO to be configured as open drain. Make sure we define this GPIO as open drain in the device tree. This gets rid of the following warning: gpio-81 (scl): enforced open drain please flag it properly in DT/ACPI DSDT/board file Note that currently the i.MX pinctrl driver does not support enabling open drain directly, so this patch has no effect in practice. Open drain is enabled by the fixed pinmux entry.
