mlxsw: spectrum: Move port module mapping before core port init
During port creation, mlxsw_core_port_init() is called with the front
panel port number and the split port sub-number. Currently, this
information is determined by the driver without firmware assistance.
Subsequent patches are going to query this information from firmware,
but this requires the port to be mapped to a module.
Therefore, move port mapping before mlxsw_core_port_init().
