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.

    Structure field, maybe? :-)
