[PULL 16/30] hw/ppc/pseries: do not require CONFIG_USB

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

From: Paolo Bonzini <pbonzini@redhat.com>

With --without-default-devices it is possible to build a binary that
does not include any USB host controller and therefore that does not
include the code guarded by CONFIG_USB.  While the simpler creation
functions such as usb_create_simple can be inlined, this is not true
of usb_bus_find().  Remove it, replacing it with a search of the single
USB bus on the machine.
