Rename ice_sbq_msg_dev to ice_sbq_dev_id to reflect the meaning of this type more precisely. This enum type describes RDA (Remote Device Access) client ids, accessible over SB (Side Band) interface. Rename enum elements to make a driver namespace more cleaner and consistent with other definitions within SB Remove unused 'rmn_x' entries, specific to unsupported E824 device. Adjust clients '2' and '13' names (phy_0 and phy_0_peer respectively) to be compliant with EAS doc. According to the specification, regardless of the complex entity (single or dual), when accessing its own ports, they're accessed always as 'phy_0' client. And referred as 'phy_0_peer' when handling ports connected to the other complex.
