    gpio_intel: Support integrated GPIO controllers of the Cherry Trail SoC.
    
    * The gpio_acpi module takes care of probing and setting up the ACPI
      GPIO-signaled events and the ACPI address space handler, utilizing the
      gpio interface provided by gpio_intel for the actual GPIO accesses.
    
    * So far gpio_intel can only be used for the ACPI-5.0 GPIO features.
    
    * This makes ACPI gpio events (which replace GPE interrupts on many
      current x86 SoC devices) work, and provides a handler for the
      GeneralPurposeIo Opregions of each GPIO controller.
    
    * With this the HP x2 210 detachable correctly recognizes unplugging
      of the power supply, and opening/closing of the lid.
    
    * Further work is still needed to refactor gpio_intel to make adding
      support for other SoC/CPU versions easier.
    
    * The gpio_if.m interface is still a prototype that only provides a
      minimum of functionality that is needed to get  gpio_acpi working.
