Forward the rx/tx timestamp machinery from the dsa infrastructure to the switch driver. On the rx side, defer delivery of skbs until we have an rx timestamp. This mimicks the behavior of skb_defer_rx_timestamp. On the tx side, identify PTP packets, clone them, and pass them to the underlying switch driver before we transmit. This mimicks the behavior of skb_tx_timestamp.

The current dsa_upstream_port() helper still assumes a unique CPU port in the whole switch fabric. This is becoming wrong, as every port in the fabric has its dedicated CPU port, thus every port has an upstream port. Add a port argument to the dsa_upstream_port() helper and fetch its CPU port instead of the deprecated unique fabric CPU port. A CPU or unused port has no dedicated CPU port, so return itself in this case. At the same time, change the return value from u8 to unsigned int since there is no need to limit the size here.

In order to know if a port is of type user, dsa_is_normal_port checks that the given port is not of type DSA nor CPU. This is not enough because a port can be unused. Without the previous fix, this caused the unused mv88e6xxx ports to be configured in normal mode. The ds->enabled_port_mask reports the user ports, so check this instead.

As the comment above the chunk states, the b53 driver attempts to disable the unused ports. But using ds->enabled_port_mask is misleading, because this mask reports in fact the user ports.

The dsa_port structure has a "netdev" member, which can be used for either the master device, or the slave device, depending on its type. It is true that today, CPU port are not exposed to userspace, thus the port's netdev member can be used to point to its master interface. But it is still slightly confusing, so split it into more explicit "master" and "slave" members inside an anonymous union.
