mlxsw: reg: Replace MID related fields in SFGC register

SFGC register maps {packet type, bridge type} -> {MID base, table type}.
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.
