cpu/intel/model_206ax: Unify ACPI C-state options

All mainboards use the same values for AC and battery, even desktop
boards without a battery. Use the AC values everywhere and drop the
battery values. Subsequent commits will rename the AC power options
accordingly, and will also clean up the corresponding acpigen code.
This is intentional so as to ease reviewing the devicetree changes.

Also update util/autoport accordingly.
