This failure path should return a negative error code but it currently
returns success.

Truncation of DMA_BIT_MASK to 32-bit dma_addr_t is semantically safe,
but the compiler was warning because it was happening implicitly.
Insert explicit casts to suppress the warnings.

We don't yet have a .sriov_configure() to create them, though.

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.
