Added new capability to the list of rx offloads for hw timestamp

The PMDs how expose this capability will always have it enabled.
But, if the following API got accepted applications can choose
between disable/enable this API.

Not sure this comment is accurate, Rx offloads are application request, PMD
does not have to enable it by default.
