mb/lenovo/*/acpi: Store the requested state wake state for bluetooth and WWAN
L520 and T420 should also use it - platforms are very similar to t420s and t530. Z61t is based on T60/X60, X131e is based on X230 so commit with Change-Id I13c08b8c6b1bf0f3deb25a464b26880d8469c005 should be applied as well. All four platforms are using ec/lenovo/h8 embedded controller.
