Subject: [PATCH v3 2/3] can: flexcan: add NXP S32G2/S32G3 SoC support

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

Add device type data for S32G2/S32G3 SoC.

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.
