There is no need to pass 'cmdsize' to the usb drivers as the cmdsize
is always 8 bytes.

Merge both the control and bulk pipe sending functions into one new
function: xhci_send_pipe(). This makes the xhci interface similar to
the other usb drivers.

Instead of exporting both xhci_alloc_pipe() and xhci_update_pipe(),
export only xhci_realloc_pipe() and support alloc, update, and free
from it.

This is just function renaming - no code implementation changes.

At least some real-world controllers require 64 byte contexts. Detect
this case and handle it appropriately.

The previous code attempts to correlate which UHCI and OHCI
controllers correlate with which EHCI controllers so that it can
ensure high speed devices are handled by the EHCI code while low/full
speed devices are handled by the UHCI/OHCI code. Replace this logic
by initializing all EHCI controllers first, and then initializing all
UHCI and OHCI controllers. This simplifies the code and improves
support for some hardware devices that don't follow the OHCI/UHCI to
EHCI correlation standard.
Also, remove the unused usb->busid field.

$subject says all. Support for usb3 streams is not implemented yet,
otherwise it is fully functional. Tested all usb devices supported
by qemu (keyboard, storage, usb hubs), except for usb attached scsi
in usb3 mode (which needs streams).
Tested on qemu only, tagged with QEMU_HARDWARE because of that.
Testing with physical hardware to be done.
