can: rcar_canfd: Add multi_channel_irqs to struct rcar_canfd_hw_info
RZ/G2L has separate IRQ lines for tx and error interrupt for each
channel whereas R-Car has a combined IRQ line for all the channel
specific tx and error interrupts.
Add multi_channel_irqs to struct rcar_canfd_hw_info to select the
driver to choose between combined and separate irq registration for
channel interrupts. This patch also removes enum rcanfd_chip_id and
chip_id from both struct rcar_canfd_hw_info, as it is unused.
