mlxsw: Support CQEv2 for SDQ in Spectrum-2 and newer ASICs
Currently, Tx completions are reported using Completion Queue Element
version 1 (CQEv1). These elements do not contain the Tx time stamp,
which is fine as Spectrum-1 reads Tx time stamps via a dedicated FIFO
and Spectrum-2 does not currently support PTP.
In preparation for Spectrum-2 PTP support, use CQEv2 for Spectrum-2 and
newer ASICs, as this CQE format encodes the Tx time stamp.
