asus-wmi: provide access to ALS control
[ Upstream commit aca234f6378864d85514be558746c0ea6eabfa8e ]
Asus Zenbook ux31a is providing ACPI0008 interface for ALS
(Ambient Light Sensor), which is accessible for OS => Win 7.
This sensor can be used with iio/acpi-als driver.
Since it is disabled by default, we should use asus-wmi
interface to enable it.
