Currently the throttle event handler method THRM is defined as an extern on the intel bd82x6x and lynxpoint chipsets, then defined again in the platform with thermal event handling. In newer versions of IASL, this generates an error, as the method is defined in two places. Simply removing the extern causes the call to it to fail on platforms where it isn't actually defined, so add a preprocessor define where it's implemented, and only call the method on those platforms. This also requires moving the thermal handler, which now includes the define to before the gnvs asl file. TEST=Build before and after, make sure correct code is included.
