thermal/drivers/tegra-bpmp: Check if BPMP supports trip points

Check if BPMP supports thermal trip points, and if not,
do not expose the .set_trips callback to the thermal core
framework. This can happen in virtualized environments
where asynchronous communication with VM BPMP drivers is not
available.
