Sansa AMS USB driver : still not working

Implement usb_enable()
Reorder/Modify usb_drv_init() to match closer the OF and remove a freeze
(USB registers were accessed before the USB module was enabled)
Add a panic in USB isr to be sure we notice when it's called
Reset GPIOA direction for usb_detect() to notice extraction
Add some comments
