FS#10107: work around the issue on some ipods where after shutdown they do not power on.
Some ipods do not power on correctly after being shut down and require a hard
reset before they work again. This workaround shuts the device down via the OF
which prevents the problem from occurring. There is a cosmetic effect: the low
battery symbol appears briefly on power of.
Change applies to PP502x ipods: 4G/photo/video/mini1g/mini2g/nano1g
Patch by Boris Gjenero (dreamlayers), manual changes by me.
