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.

FlexCAN module from S32G2/S32G3 is similar with i.MX SoCs, but interrupt management is different. This initial S32G2/S32G3 SoC FlexCAN support paves the road to address such differences.
