ravb: Add stats_len to struct ravb_hw_info
R-Car provides 30 device stats, whereas RZ/G2L provides only 15. In addition, RZ/G2L has stats "rx_queue_0_csum_offload_errors" instead of "rx_queue_0_missed_errors". Replace RAVB_STATS_LEN macro with a structure variable stats_len to struct ravb_hw_info, to support subsequent SoCs without any code changes to the ravb_get_sset_count function.
