sfc: support X4 devlink flash 



Unlike X2 and EF100, we do not attempt to parse the firmware file to
 find an image within it; we simply hand the entire file to the MC,
 which is responsible for understanding any container formats we might
 use and validating that the firmware file is applicable to this NIC.
