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 http://bugzilla.kernel.org/show_bug.cgi?id=6723 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.
