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.

v3: Back to runtime detection, but more simple this time compared to v1
(checking for OHCI should be enough, since this implies CONFIG_USB
which is the switch that usb-kbd and usb-tablet are depending on)
