Hi,

On x86 the fist idle state is a polling one, but the way it is set up is far
from straightforward and then it is avoided by governors in rather somewhat
convoluted fashion.

Make this more clear by explicitly flagging that state as "polling" and
checking its flag where it needs to be avoided instead of using
arch-dependent numbering of idle states (patch [1/3]), move the
polling state code from driver.c to a separate C file (patch [2/3]) and
move the initialization of it from the core to the relevant cpuidle drivers -
ACPI and intel_idle (patch [3/3]).

Thanks,
Rafael
