ice: Add ice_get_link_status_datalen

Browse Source 
The Get Link Status data length can vary with different versions of
ice_aqc_get_link_status_data. Add ice_get_link_status_datalen() to return
datalen for the specific ice_aqc_get_link_status_data version.
Add new link partner fields to ice_aqc_get_link_status_data; PHY type,
FEC, and flow control.
