    intel_idle: delete power_policy modparam, and choose substate functions

    The idea behind power policy was that it would start off as a modparam,
    and then hook into the new "global" in-kernel power vs energy tunable.
    But that tunable isn't happening, so delete the hook here.

    With the policy hook gone, the sub-state choice functions
    do not do anything useful, so delete them from the critical path.

    To handle sub-states in the future, we will advertise them
    with dedicated cpuidle_state entries. That is necessary
    because some of the sub-states will have substantially different
    properties than their peer sub-states.
