Compared to Icelake, Tigerlake's MAX_CONTEXT_HW_ID is smaller by one, but
since we just use the upper 32 bits of the lrc_desc, it's guaranteed OA
will use the correct one.

This looks correct, I just have one question I don't remember the answer
to :
With GuC on Gen11+ we get the same value as when i915 builds up the
upper 32bits of the LRC descriptor using the hw_id?
Thanks,
