New timestamping API was introduced in commit 66f7223039 ("net: add
NDOs for configuring hardware timestamping") from kernel v6.6. It is
time to convert the mlxsw driver to the new API, so that the
ndo_eth_ioctl() path can be removed completely.
The UAPI is still ioctl-only, but it's best to remove the "ioctl"
mentions from the driver in case a netlink variant appears.
