sfc: Refactor link configuration
Refactor PHY, MAC and NIC configuration operations so that the existing link configuration can be re-pushed with: efx->phy_op->reconfigure(efx); efx->mac_op->reconfigure(efx); and a new configuration with: efx->nic_op->reconfigure_port(efx); (plus locking and error-checking). We have not held the link settings in software (aside from flow control), and have relied on asking the hardware what they are. This is a problem because in some cases the hardware may no longer be in a state to tell us. In particular, if an entire multi-port board is reset through one port, the driver bindings to other ports have no chance to save settings before recovering. We only actually need to keep track of the autonegotiation settings, so add an ethtool advertising mask to struct efx_nic, initialise it in PHY init and update it as necessary. Remove now-unneeded uses of efx_phy_op::{get,set}_settings() and struct ethtool_cmd. Much of this was done by Steve Hodgson <shodgson@solarflare.com>.
