<pre>commit c210e85b8f3371168ce78c8da00b913839a84ec7 (HEAD -> drm-intel-next-queued,
drm-intel/drm-intel-next-queued)

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...
