There are some H/W differences for the gPTP feature between
R-Car Gen3, R-Car Gen2, and RZ/G2L as below.

1) On R-Car Gen3, gPTP support is active in config mode.
2) On R-Car Gen2, gPTP support is not active in config mode.
3) RZ/G2L does not support the gPTP feature.

Add a ptp_cfg_active hw feature bit to struct ravb_hw_info for
supporting gPTP active in config mode for R-Car Gen3.
   Wait, we've just done this ion the previous patch!

This patch also removes enum ravb_chip_id, chip_id from both
struct ravb_hw_info and struct ravb_private, as it is unused.

   What's that? Didn't you touch this lie in patch #3?

   This seems lie a NAK bait... :-(
