dt-bindings: can: renesas,rcar-canfd: Simplify the conditional schema 



RZ/G3E SoC has 20 interrupts, 2 resets and 6 channels that need more
branching with conditional schema. Simplify the conditional schema with
if statements rather than the complex if-else statements to prepare for
supporting RZ/G3E SoC.
