Fix imx pinctrl dt flat functions default return value.
If property fsl,pins is not found in function_np and
pinctrl_np return false to indicate that DT is not using
flat functions.

The for loop in this function checks the child nodes and the child's
child nodes. Therefore if we exit the for loop we didn't find any nodes
on any level with the 'fsl,pins' property.

So this 'default' return value is never used unless there is no fsl,pins
property anywhere. So this return value is not important but I wrote
true because we want to use the new flat dt option as default. The extra
indention doesn't make sense anymore.

Regards,

Markus
