On RZ/G2L SoC interrupt sources for each channel are split into different sources and the IP doesn't divide (1/2) CANFD clock within the IP. This patch adds compatible string for RZ/G2L family and registers the irq handlers required for CANFD operation. IRQ numbers are now fetched based on names instead of indices. For backward compatibility on non RZ/G2L SoC's we fallback reading based on indices.
