ravb: Add gstrings_stats and gstrings_size to struct ravb_hw_info
The device stats strings for R-Car and RZ/G2L are different. 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". Add structure variables gstrings_stats and gstrings_size to struct ravb_hw_info, so that subsequent SoCs can be added without any code changes in the ravb_get_strings function.
