mb/siemens/{mc_apl1,...,mc_apl5}: Fix GPIO settings
Correct all GPIOs with reference to the Apollo Lake SoC EDS Vol 4
revision 2.4 chapter 10.1.2.3 List of Pins that are GPIOs but cannot be
used in Function 0 (GPIO) mode.
In additional, set an internal pull to any GPI that does not have an
external resistor so that the input is not in an undefined state.
