USB bugfixes for 3.3-rc4

A number of new device ids, and a cleanup/fix for some of the option
device ids that shouldn't have been added in the first place.

There's also a few USB 3 fixes for problems that people have reported,
and a usb-storage bugfix to round it out.

Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* tag 'usb-3.3-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb:
  USB: Added Kamstrup VID/PIDs to cp210x serial driver.
  USB: Serial: ti_usb_3410_5052: Add Abbot Diabetes Care cable id
  usb-storage: fix freezing of the scanning thread
  xhci: Fix encoding for HS bulk/control NAK rate.
  USB: Set hub depth after USB3 hub reset
  USB: Fix handoff when BIOS disables host PCI device.
  USB: option: cleanup zte 3g-dongle's pid in option.c
  USB: Don't fail USB3 probe on missing legacy PCI IRQ.
  xhci: Fix oops caused by more USB2 ports than USB3 ports.
  USB: Remove duplicate USB 3.0 hub feature #defines.
