tests drivers: can: fails at nrf54h20 - assertion at icmsg

[nordic-piks]

Describe the bug The tests:

• tests/drivers/can/timing/drivers.can.timing
• tests/subsys/canbus/isotp/conformance/canbus.isotp.conformance.fd.txdl_32
• tests/subsys/canbus/isotp/conformance/canbus.isotp.conformance
• tests/subsys/canbus/isotp/implementation/canbus.isotp.implementation
• tests/drivers/can/api/drivers.can.api
• tests/drivers/can/api/drivers.can.api.rtr
• tests/drivers/can/shell/drivers.can.shell
• tests/subsys/canbus/isotp/conformance/canbus.isotp.conformance.fd.unused
• tests/subsys/canbus/isotp/conformance/canbus.isotp.conformance.fd.txdl_64

Observed for

• nrf54h20dk/nrf54h20/cpuap

To Reproduce Steps to reproduce the behavior:

1. have nrf54h20dk/nrf54h20/cpuap connected
2. go to your zephyr dir
3. call ./scripts/twister -T tests/drivers/can/timing -p nrf54h20dk/nrf54h20/cpuapp --device-testing --device-serial /dev/ttyACM0 -v --inline-logs
4. See console output with error

Expected behavior Valid console output

Impact Not clear
