acpi_handle_list is used to store the references returned by
ThermalZone._PSL. With processors supporting Hyper-threading and more
cores, the previous limit is not enough for common cases. If _PSL
returns more than the limit, the passive thermal threshold fails to
initialize.

This change increase the limit to 32, so we can support at least 16 core
CPUs with Hyper-threads.

I acknowledge that this change is just kicking the can down the road.
