98ff4c7c8a sfc: Separate netdev probe/remove from PCI probe/remove
The netdev probe will be used when moving from vDPA to EF100 BAR config.
The netdev remove will be used when moving from EF100 to vDPA BAR config.

In the process, change several log messages to pci_ instead of netif_
to remove the "(unregistered net_device)" text.

51b35a454e sfc: skeleton EF100 PF driver
No TX or RX path, no MCDI, not even an ifup/down handler.
Besides stubs, the bulk of the patch deals with reading the Xilinx
 extended PCIe capability, which tells us where to find our BAR.

Though in the same module, EF100 has its own struct pci_driver,
 which is named sfc_ef100.

A small number of additional nic_type methods are added; those in the
 TX (tx_enqueue) and RX (rx_packet) paths are called through indirect
 call wrappers to minimise the performance impact.
