[PULL 02/10] hw/mips: Improve the default USB settings in the loongson3-virt machine

[Philippe Mathieu-Daudé]

From: Thomas Huth <thuth@redhat.com>

It's possible to compile QEMU without the USB devices (e.g. when using
"--without-default-devices" as option for the "configure" script).
To be still able to run the loongson3-virt machine in default mode with
such a QEMU binary, we have to check here for the availability of the
OHCI controller first before instantiating the USB devices.
