Dereferencing hcd.pdev will always oops with SA-1111.  It has to be
treated as a cookie, not a pointer in any common OHCI HCD code.

Apparently we need a clean way to go from struct device * to struct
ohci_hcd *.  I added dev_to_ohci that does the obvious thing and added
separate implementations for PCI and SA-1111.  Two implementations is
ugly but I didn't think it wise (for me) to hack on the PCI/driverfs
interface, so I just cut & paste the old code.

Two patches.  The first is a diff from linux-2.5.44 and
linux-2.5.44-rmk1.  It is from rmk and adds a struct device pointer to
ohci_hcd.  The second depends on the first and contains my changes to
clean up to the pdev oops problems.  (Some fuzz may occur as I have
ohci-1024 applied.)

With these changes, SA111 OHCI-HC/HCD is showing some signs of life on
linux-2.5.44-rmk1.  usb-storage is currentl blowing chunks, but I think
I saw some patches go by against 2.5.44 that I haven't yet tried.
