pinctrl: clarify some dt pinconfig options
The bias-pull-* options use values > 0 to indicate that the pull should be activated and optionally also indicate the strength of the pull. Therefore use an default value of 1 for these options. Split the low-power-mode option into low-power-enable and -disable. Update the documentation to describe the param arguments better.
