intel bd82x6x/lynxpoint systems: Update ACPI thermal zone handler

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.
