hwmon: (dell-smm) Disallow fan_type() calls on broken machines
Some Dell machines have especially broken SMM or BIOS which cause that once fan_type() is called then CPU fan speed going randomly up and down. And for fixing this behaviour reboot is required. So this patch creates fan_type blacklist of affected Dell machines and disallow fan_type() call on them to prevent that erratic behaviour. Old blacklist which disabled loading driver on some machines added in commits a4b45b25f18d ("hwmon: (dell-smm) Blacklist Dell Studio XPS 8100") and 6220f4ebd7b4 ("hwmon: (dell-smm) Blacklist Dell Studio XPS 8000") were moved to FAN_TYPE blacklist.
