Benjamin Herrenschmidt c1e0cc7e1d nvme-pci: Add support for variable IO SQ element size ...

The size of a submission queue element should always be 6 (64 bytes)
by spec.

However some controllers such as Apple's are not properly implementing
the standard and require a different size.

This provides the ground work for the subsequent quirks for these
controllers.
