drivers/net/vsc9953: Add command to show/clear port counters
The new added command:
ethsw [port <port_no>] statistics { [help] | [clear] }
will print counters like the number of Rx/Tx frames,
number of Rx/Tx bytes, number of Rx/Tx unicast frames, etc.
This patch also adds this commnd in the genereric ethsw
parser from cmd_ethsw.c
