pinctrl: more clarifications for generic pull configs
PULL_PIN_DEFAULT is meant for hardware completely hiding any pull settings from the driver, so that it's really only possible to turn the pull on or off, but it not being possible to determine any pull settings from software. Also the binding-documentation for the pull arguments did not match the changes to the expected values.

-- bias-pull-up, -down and -pin-default take as optional argument 0 to disable
- the pull, on hardware supporting it the pull strength in Ohm. bias-disable
- will also disable any active pull.
