thermal: ACPI: Make helpers retrieve temperature only

Browse Source 
It is slightly better to make the ACPI thermal helper functions retrieve
the trip point temperature only instead of doing the full trip point
initialization, because they are also used for updating some already
registered trip points, in which case initializing a new trip just
in order to update the temperature of an existing one is somewhat
wasteful.

Modify the ACPI thermal helpers accordingly and update their users.

No intentional functional impact.
