thermal: ACPI: Initialize trips if temperature is out of range

In some cases it is still useful to register a trip point if the
temperature returned by the corresponding ACPI thermal object (for
example, _HOT) is invalid to start with, because the same ACPI
thermal object may start to return a valid temperature after a
system configuration change (for example, from an AC power source
to battery an vice versa).

For this reason, if the ACPI thermal object evaluated by
thermal_acpi_trip_init() successfully returns a temperature value that
is out of the range of values taken into account, initialize the trip
point using THERMAL_TEMP_INVALID as the temperature value instead of
returning an error to allow the user of the trip point to decide what
to do with it.

Also update pch_wpt_add_acpi_psv_trip() to reject trip points with
invalid temperature values.
