[PATCH v2 1/2] dt-bindings: pinctrl: apple,pinctrl: Add t8140 compatible

[Yureka Lilian]

The pinctrl_ap GPIO controller on the MacBook Neo crashes upon reading
REG_GPIOx for certain pins. These pins, which are also listed in Apple's
device tree, are described by the gpio-reserved-ranges property.
