USB: add an ohci board-specific quirk

Use the new ohci-pci quirk infrastructure to address the problem it was
created to address: a quirk specific to the Portege 4000, in buzilla as

Also fix a misuse of "__devinit" for the quirk functions.  It must not
be used without first ensuring that the references from the quirk tables
are gone, and that the function using those quirk tables is also gone.
