A new OHCI day

OHCI now seems to work a lot better, and my USB stack now correctly only
resets one port at a time and initializes that one instead of first
reseting ALL ports and then trying the whole address 0 stuff

* After testing my OS on 4 different real computers, I have now fixed
some issues relating to uninitialized spinlocks and my memory manager..
It is wierd that ACPICA seems to fail the EnableSubSystem call on some
computers though :p
