[PATCH net-next v11 13/13] netlink: specs: tsinfo: Enhance netlink attributes and add a set command

[Kory Maincent]

Add new attributed to tsinfo allowing to get the tsinfo and the hwtstamp
from a phc provider (composed by a phc index and a phc qualifier) on a
netdevice's link.
Add simultaneously a set command to be able to set hwtstamp configuration
for a specified phc provider.

Here is few examples:
