    drm/i915/tgl: Extend MI_SEMAPHORE_WAIT
    On Tigerlake, MI_SEMAPHORE_WAIT grew an extra dword, so be sure to
    update the length field and emit that extra parameter and any padding
    noop as required.
    v2: Define the token shift while we are adding the updated MI_SEMAPHORE_WAIT
    v3: Use int instead of bool in the addition so that readers are not left
    wondering about the intricacies of the C spec. Now they just have to
    worry what the integer value of a boolean operation is...
