* remotes/kraxel/tags/pull-usb-20150218-1:
  Make sysbus EHCI devices ARM only by default
  PPC: Don't use legacy -usbdevice support for setting up board
  r2d: Don't use legacy -usbdevice support for setting up board
  usb: Change usb_create_simple() to abort on failure
  usb: Suppress bogus error when automatic usb-hub creation fails
  usb: Do not prefix error_setg() messages with "Error: "
  usb: Improve -usbdevice error reporting a bit
  usb: usb_create() can't fail, drop useless error handling
