[PATCH v4 01/11] dt-bindings: can: renesas,rcar-canfd: Simplify the conditional schema

[Biju Das <biju.das.jz@bp.renesas.com>]

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.
