Subject: [net-next V2 12/13] net/mlx5e: Cleanup PTP

From: Aya Levin <ayal@...dia.com>

Reduce scope of mlx5e_ptp_params, move to its c file. Remove unneeded
variables from mlx5e_ptp_open and state bitmap from PTP channel. In
addition, remove channel index from PTP channel since it is set to a
hard coded value, use define instead.
