mlxsw: core_linecards: Probe active line cards for devices and expose FW version

Browse Source 
In case the line card is active, go over all possible existing
devices (gearboxes) on it and expose FW version of the flashable one.

Example:

$ devlink dev info auxiliary/mlxsw_core.lc.0
auxiliary/mlxsw_core.lc.0:
  versions:
      fixed:
        hw.revision 0
      running:
        ini.version 4
        fw 19.2010.1312
