This reworks the ACPI thermal driver to use a table of generic trip
point structures on top of the internal representation of trip points
and removes thermal zone callbacks that are not necessary any more
from it.

It requires some relatively small changes to be made in the thermal core
too and it is based on top of changes reworking ACPI device notification
handling that are included in this merge.
