dt-bindings: input: microchip,cap11xx: Add reset-gpios property
Add support for the optional reset-gpios property to describe
the active-high reset pin for CAP1126/CAP1188 devices.
Driving the GPIO high asserts reset and deep sleep, while driving
it low releases reset for normal operation.
Restrict this property to be available only on CAP1126 and CAP1188
chips, as other CAP11xx variants do not have a hardware reset pin.
