The CAN FD IP found on RZ/G2L SoC has some HW features different to that
of R-Car. For example, it has multiple resets and multiple IRQs for global
and channel interrupts. Also, it does not have ECC error flag registers
and clk post divider present on R-Car. Similarly, R-Car V3U has 8 channels
whereas other SoCs has only 2 channels.
This patch adds the struct rcar_canfd_hw_info to take care of the
HW feature differences and driver data present on both IPs. It also
replaces the driver data chip type with struct rcar_canfd_hw_info by
moving chip type to it.
Whilst started using driver data instead of chip_id for detecting
R-Car V3U SoCs.
