parlio_rx_pulse_delimiter_config_t::valid_sig_line_id field

The data line id of valid/enable signal. The selected data line will be used as the valid/enable signal (i.e. pulse signal) in this delimiter. As the line of valid/enable signal is shared with the data line, this line_id will be conflict with the data line if set the id within 'data_width', therefore the range is (data_width, PARLIO_RX_UNIT_MAX_DATA_WIDTH].
