Make it possible to have an empty GPIOs in a GPIO list for device. For example a SPI master may use both GPIOs and native pins as chip selects and we need to be able to distinguish between the two. This makes it mandatory to have exactly 3 arguments for GPIOs and then converts gpiolib to use of __acpi_node_get_property_reference() instead. In addition we make acpi_gpio_package_count() to handle holes as well (this matches the DT version). Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Acked-by: Rafael J.
