wr_si57x_interface: seems SI_START2 state is never reached

SI_START2 state seems to be never reached by the current FSM here: https://ohwr.org/project/wr-cores/blob/proposed_master/modules/wr_si57x_interface/wr_si57x_interface.vhd#L326

Maybe line 324 (https://ohwr.org/project/wr-cores/blob/proposed_master/modules/wr_si57x_interface/wr_si57x_interface.vhd#L324) should have been:

f_i2c_iterate(i2c_tick, seq_count, x"00", STOP, scl_out_fsm, sda_out_fsm, state, SI_START2);

instead of:

f_i2c_iterate(i2c_tick, seq_count, x"00", STOP, scl_out_fsm, sda_out_fsm, state, IDLE);

Thanks!
