As preparation for unified bridge model, remove 'mid' field and add 'mid_base' field. The MID index (index to PGT table which maps MID to local port list and SMPE index) is a result of 'mid_base' + 'fid_offset'. Using the legacy bridge model, firmware configures 'mid_base'. However, using the new model, software is responsible to configure it via SFGC register. The 'mid_base' is configured per {packet type, bridge type}, for example, for {Unicast, .1Q}, {Broadcast, .1D}. Add the field 'mid_base' to SFGC register and increase the length of the register accordingly. Remove the field 'mid' as currently it is ignored by the device, its use is an old leftover.
