common/sfc_efx/base: support link status change v2 events

FW should send link status change events in either v1 or v2 format
depending on the preference which the driver can express during
CMD_DRV_ATTACH stage. At the moment, libefx does not request v2, so v1
events must arrive.
However, FW does not honour this choice and always sends v2 events.

So teach libefx to parse such and add v2 request to CMD_DRV_ATTACH,
correspondingly.
