dt-bindings: pinctrl: qcom: Define common TLMM binding 



Several properties are shared between all TLMM bindings. By providing a
common binding to define these properties each platform's binding can be
reduced to just listing which of these properties should be checked for
- or further specified.

  Mode Multiplexer bindings and pinconf/pinmux states for these.

    description:

      Pins can be reserved for trusted applications and thereby unaccessible

      from the OS.  This property can be used to mark the pins which resources

      should not be accessed by the OS. Please see the ../gpio/gpio.txt for more

      information.
