Fix low-level OHCI transfers for ARM920t and MPC5xxx

Browse Source 
A new, Windows compatible init sequence was also backported from Linux 2.6,
but disabled with #undef NEW_INIT_SEQ as it wouldn't change the behaviour
of the memopry sticks we tested. Maybe it's not relevant for mass storage
devices. For recerence, see file common/usb.c, function usb_new_device(),
section #ifdef NEW_INIT_SEQ.
