iPod Classic: use PMU interrupts to detect accessories

Browse source 
- Speed auto detection is launched when an accessory is inserted,
  so the user doesn't need to modify settings to use accessories
  that operates at different speeds (or when the same accessory is
  unplugged and plugged again).

- UART controller is disabled when no accessory is inserted, not
  much powersave but everything counts.
