Merge recent USB2/EHCI related changes from NetBSD:

 o Reduce the interrupt delay to 2 microframes.
 o Follow the spec more closely when updating the overlay qTD in the QH.
 o No need to generate an interrupt at the data part of a control
   transfer, it's generated by the status transfer.
 o Make sure to update the data toggle on short transfers.
 o Turn the printf about needing toggle update into a DPRINTF.
 o Keep track of what high speed port (if any) a device belongs to
   so we can set the transaction translator fields for the transfer.
 o Verbosely refuse to open low/full speed pipes that depend on
   unimplemented split transaction support.
 o Fix various typos in comments.
