ACPI: OSI: Add DMI quirk for Acer Aspire One D255
The screen backlight turns off during boot (specifically during udev device
initialization) when returning true for _OSI("Windows 2009").
Analyzing the device's DSDT reveals that the firmware takes a different
code path when Windows 7 is reported, which leads to the backlight shutoff.
Add a DMI quirk to invoke dmi_disable_osi_win7 for this model.
