    drivers/i2c/generic: Allow mainboards to export reset and enable GPIOs
    
    Add power management type config option that allows mainboards to
    either:
    1. Define a power resource that uses the reset and enable gpios to
    power on and off the device using _ON and _OFF methods, or
    2. Export reset and enable GPIOs in _CRS and _DSD so that the OS can
    directly toggle the GPIOs as required.
    
    GPIO type needs to be updated in drivers_i2c_generic_config to use
    acpi_gpio type so that it can be used for both the above cases.
    
    BUG=chrome-os-partner:60194
    BRANCH=None
    TEST=Verified that elan touchscreen works fine on reef using exported
    GPIOs.
