In ef100_reset(), make the MCDI call to do the reset.
Also, do a reset at start-of-day during probe, to put the function in
a clean state.

MC_CMD_GET_CAPABILITIES now has a third word of flags; extend the
efx_has_cap() machinery to cover it.

Currently RX and TX-completion events are unhandled, as neither the RX
nor the TX path has been implemented yet.

Channels are probed, but actual event handling is still stubbed out.
Stub implementation of check_caps is needed because ptp.c will call into
it from efx_ptp_use_mac_tx_timestamps() to decide if it wants TXQs.

We can't actually do the MCDI to probe it fully until we have working
MCDI, which comes later, but we need efx->phy_data to be allocated so
that when we get MCDI events the link-state change handler doesn't
NULL-dereference.

We don't actually do the efx_mcdi_reset() because we don't have MCDI yet.

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.
