[Pinephone][Feature Request] restart desktop per HW switches
Sometimes GUI applications and the whole DE become unresponsive. In these cases, the pinephone is still reachable via e.g. SSH and mostly responsive.
This state can end through:
- "timeout", i.e. letting things run their course (can take minutes until "forever")
- hard restart of the phone (hard shutdown via button/removal of the battery + normale boot)
Another solution would be a way to manually restart the desktop environment through a physical key combination. I'd suggest employing PWR+VolDn or PWR+VolUp (as is done in Android phones for (temporarily/manually) "disconnecting the battery" to achieve a hard reboot
