[PATCH 1/3] dt-bindings: can: fsl,flexcan: add S32G2/S32G3 SoC support

[Ciprian Costea <ciprianmarian.costea@oss.nxp.com>]

From: Ciprian Marian Costea <ciprianmarian.costea@oss.nxp.com>

Add S32G2/S32G3 SoCs compatible strings.

A particularity for these SoCs is the presence of separate interrupts for
state change, bus errors, MBs 0-7 and MBs 8-127 respectively.

Increase maxItems of 'interrupts' to 4 for S32G based SoCs and keep the
same restriction for other SoCs.

Also, as part of this commit, move the 'allOf' after the required
properties to make the documentation easier to read.
