Each subsystem would like to have its own say on what the restart level should be for their particular device. Instead of having a global knob that chooses the subsystem restart level, have a per subsystem restart level so that each subsystem can choose their own restart level. Do this by introducing a per-device sysfs knob that can be written with a string indicating the restart level for that device. "SYSTEM" will reset the entire system when a subsystem crashes, while "RELATED" will restart the subsystem and the group of subsystems related to the subsystem that crashed. Independent used to be possible, but we remove it here because it is equivalent to "RELATED". Also independent restart can cause confusion if the hardware really doesn't support independent restart and the user attempts to choose the independent restart level. Let's not expose broken options to userspace. Some code was using get_restart_level() to determine the global restart level. Luckily most of that code was doing purely debugging things so just remove it and update the last few callers to use a new device call, subsys_get_restart_level(), so they can determine what userspace has chosen for their device.
