[PATCH 1/2] pinctrl: pmic-mpp: Add missing dt-bindings mpp function defs

[Konrad Dybcio]

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@xxxxxxxxxxxxxx>

The pinctrl-spmi-mpp driver supports setting more mpp functions
than the ones defined in the dt-bindings header, specifically,
digital, analog and sink.

To follow the current way of specifying the function config
in Device-Tree, add the missing three definitions in the
appropriate dt-bindings header as:
GPIO_MPP_FUNC_{DIGITAL,ANALOG,SINK}.
