From: Biju Das <biju.das.jz@bp.renesas.com>
The calculation formula for nominal bit rate of classical CAN is same as
that of nominal bit rate of CANFD on the RZ/G3E and R-Car Gen4 SoCs
compared to other SoCs. Update nominal bit rate constants.
Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>
---
v2->v3:
* Replaced "shared_bittiming"->"shared_can_regs" as it is same for RZ/G3E
and R-Car Gen4.
* Dropped the tags as it is new change.
* Updated commit header and description.
v1->v2:
* No change.
