linux-yocto/3.8: qemumips graphical boot 

Updating the meta SRCREV to fix and illegal instruction that is seen
when launching X with USB pointing devices.

    meta/qemumips: build USB_UHCI_HCD into the kernel

    When booting qemumips and USB_UHCI_HCD built as a module, the following
    trace is seen, and then prevents X from starting:

       qemumips user.warn kernel: Call Trace:

       qemumips user.warn kernel: ---[ end trace 8a48c6046870f8c2 ]---

    Building the module into the kernel fixes the problem, but the root
    cause is still under investigation. The pipelines around jumps to
    module addresses seem to be triggering invalid instructions.
