Declare power state constraints for a device in devicetree. It allows a map between device instances and power states that disable their power. This information is used by a new API (pm_policy_device_power_lock_put/get) that automically set/release pm state constraints. Signed-off-by: Flavio Ceolin <flavio.ceolin@intel.com>
