can: rcar_canfd: fix channel specific IRQ handling for RZ/G2L
commit d887087 upstream. RZ/G2L has separate channel specific IRQs for transmit and error interrupts. But the IRQ handler processes both channels, even if there no interrupt occurred on one of the channels. This patch fixes the issue by passing a channel specific context parameter instead of global one for the IRQ register and the IRQ handler, it just handles the channel which is triggered the interrupt.
