ec/lenovo/h8: Add Kconfig to select use of Thermal Zone 1

Looking at the ACPI dumps of many older Thinkpads, most do not have a
second thermal zone (zone 1), they only use zone 0. This doesn't seem
to be a problem for most boards in the tree currently, but newer boards
(such as the T480) are reporting critical temperature errors on zone 1,
due to differences in the EC RAM layout (ie, TMP1 is not valid).

To mitigate this issue with the T480 (and likely other newer boards),
only include the ACPI code for thermal zone 1 for boards which need it.
Explicitly select it for those boards based on ACPI dump analysis and
model similarity.
