ARM: dts: imx6dl: Add trip points to thermal zones on several devices

Kernel v6.3-rc1 prints errors due to missing trip points in thermal
zones. These errors indicate a lack of critical temperature threshold
settings, causing warnings at boot. To silence these errors, this patch
introduces trip points into the thermal zones of several imx6dl based
devices.

The following devices are updated:
- plym2m
- prtvt7
- victgo
- vicut1

These devices are automotive grade and expected to operate up to 105C.
An exception is the plym2m, an industrial grade device, which is
certified to work up to 85C.

The added trip points act as alert thresholds but do not trigger any
actions except warnings. This behavior is by design, as these devices
should maintain their performance until the end, without any thermal
throttling.
