FS#12083 - Add delay to usb-s3c6400x init to fix usb hang on some ipod classics

This fixes usb mode in rb hanging on my classic 120GB. Starting with usb connected still hangs though… does that work on other classics?

Slightly better patch that uses udelays instead of delay loops and makes the delays as long as the bootrom uses, also changes the order of a few things to be more similar to the bootrom. The hang when booting with usb connected is still present, it hangs when waiting for GRSTCTL & 1, i think that's unrelated.

Changed usb_drv_exit to do the powerdown like the bootrom does and it seems to have fixed the hang on startup, the order of some writes is slightly different, set more bits in ORSTCON and add in delays for good measure.

2 people reported that this patch caused usb connections to be successfully established less often on their nano2g's so i guess it needs more investigation.
