Intel i945: ACPI: Add _OSC method

Add the ACPI Operating System Capabilities Method and let the
    operation system control everything.

Commit »AMD Fam14 DSDT: Add OSC method« (00a0e76b) [1] is used as
    a template.

The Lenovo X60 [2] running the Parabola GNU/Linux distribution [3] is
    used for testing.

Before that change:
