[PATCH 1/3] platform/x86: int3472/discrete: Refactor GPIO to sensor mapping

[Hans de Goede <hdegoede@redhat.com>]

Make the GPIO to sensor mapping more generic and fold the
INT3472_GPIO_TYPE_RESET and INT3472_GPIO_TYPE_POWERDOWN cases into
a single generic case.

This is a preparation patch for further GPIO mapping changes.
