    drm/i915: Move the irq wait queue initialisation into the ring init

    Required so that we don't obliterate the queue if initialising the
    rings after the global IRQ handler is installed.

    drm/i915: Disable all outputs early, before KMS takeover

    If the outputs are active and continuing to access the GATT when we
    teardown the PTEs, then there is a potential for us to hang the GPU.
    The hang tends to be a PGTBL_ER with either an invalid host access or
    an invalid display plane fetch.
