[PATCH v6 3/4] dt-bindings: can: renesas,rcar-canfd: Document RZ/G3L SoC

[Biju Das]

Document the RZ/G3L (R9A08G046) SoC support.

RZ/G3L has 11 interrupts and 3 CANFD channels compared to 8 interrupts
and 2 CANFD channels on RZ/G3S. RZ/G3L has 288 buffers in total
compared to 192 buffers in RZ/G3S.

Like RZ/G3S, RZ/G3L supports only CAN-FD mode, so renesas,no-can-fd is
disallowed for it.

---
v5->v6:
 * Updated commit description.
 * Dropped adding RZ/G3L in the description of renesas,no-can-fd as the
   description is generic.
v4->v5:
 * Dropped the tags as there are new changes.
 * Updated the description for renesas,no-can-fd to document RZ/G3L has no
   Classical CAN mode.
 * Restored maxItems on interrupts and interrupt-names.
 * Added resets/reset-names required property for RZ/G3L.
v3->v4:
 * Dropped maxItems from interrupts,interrupt-names and resets.
 * Collected tag.
v2->v3:
 * Collected tag.
v1->v2:
 * Updated commit description
 * Dropped RZ/G3S fallback as there are lot of differences.
