This patch ensures that the ACPI cpuidle driver sets those dummy power
values itself whenever it (re-)initializes its idle states.
Tested and verified on an Acer AC700 Chromebook, which supports the C3
state only when it switches from AC to battery power.

Their absence didn't cause any kernel compilation problems, but it may
well in the future (or when compiling things in a different context,
