qemu-system-arm crash (hardware error: tsc210x_txrx: FIXME: bad SPI word width 24)
Description of problem:
The `tests/avocado/machine_arm_n8x0.py:N8x0Machine.test_n800` will sometimes trigger situation where the test does not progress and ends up interrupted.  One example is [here](https://gitlab.com/qemu-project/qemu/-/jobs/1796742618#L242):

```
(075/171) tests/avocado/machine_arm_n8x0.py:N8x0Machine.test_n800:  INTERRUPTED: Test interrupted by SIGTERM\nRunner error occurred: Timeout reached\nOriginal status: ERROR\n{'name': '075-tests/avocado/machine_arm_n8x0.py:N8x0Machine.test_n800', 'logdir': '/builds/qem
```
Steps to reproduce:
1. ./tests/venv/bin/avocado assets fetch tests/avocado/machine_arm_n8x0.py
2. nc -l -U /var/tmp/qemu-monitor.sock
3. ./qemu-system-arm -display none -vga none -chardev socket,id=mon,path=/var/tmp/qemu-monitor.sock -mon chardev=mon,mode=control -machine n800 -serial null -chardev socket,id=console,path=/var/tmp/qemu-51887-console.sock,server=on,wait=off -serial chardev:console -kernel $HOME/avocado/data/cache/by_location/07af9de13713c2905e8c6a88d6600eb1bc885c5c/meego-arm-n8x0-1.0.80.20100712.1431-vmlinuz-2.6.35~rc4-129.1-n8x0 -append 'printk.time=0 console=ttyS1'
