ec/system76/ec: acpi: Add dGPU thermal reporting

Add a new config for boards with dGPUs to enable reporting fan duty and
temperature. The dGPU is not yet enabled on any boards, so it always
reports the temp as 0. However, the EC firmware does use the dGPU's fan
and so reports valid information for fan speed.
