sfc: Add X4 PF support

sfc: Add X4 PF support

Add X4 series. Most functionality is the same as previous
EF10 nics but enough is different to warrant a new nic type struct
and revision; for example legacy interrupts and SRIOV are
not supported.

Most removed features will be re-added later as new implementations.
