This adds correct processing of the done queue of the OHCI host controller (HC). We will always process the done queue after a control or bulk transfer. Unfortunately, it's hard to tell when the HC will write out the done queue, so we have do free the transfer descriptors later and have to allocate them one by one. To distinguish different types of TDs (e.g. async vs. interrupt transfers) on the done queue, they are flagged in the lsb of there .config field. We can utilize this bit for our own purpose, as it's reserved and the host controller won't interpret it and preserves its state.
