Another issue with the Apple T2 based 2018 controllers seem to be
that they blow up (and shut the machine down) if there's a tag
collision between the IO queue and the Admin queue.
My suspicion is that they use our tags for their internal tracking
and don't mix them with the queue id. They also se
The size of a submission queue element should always be 6 (64 bytes)

However some controllers such as Apple's are not properly implementing

This provides the ground work for the subsequent quirks for these

This adds support for Apple weird implementation of NVME in their
