iio: acpi: Add support for ACPI0008 Ambient Light Sensor This driver adds the initial support for the ACPI Ambient Light Sensor as defined in Section 9.2 of the ACPI specification (Revision 5.0) [1]. Sensors complying with the standard are exposed as ACPI devices with ACPI0008 as hardware ID and provide standard methods by which the OS can query properties of the ambient light environment the system is currently operating in. This driver currently allows only to get the current ambient light illuminance reading through the _ALI method, but is ready to be extended extended to handle _ALC, _ALT and _ALP as well.
