When a TD is completed, the HC writes the content of HcDoneHead to
the NextTD field of the TD. The HC then overwrites the content of
HcDoneHead with the address of this TD. This is set to zero whenever
the HC writes the content of this register to HCCA. It also sets the
WritebackDoneHead field of HcInterruptStatus.
