[ Upstream commit 8503a4b1a24d32e95f3a233062e8f1dc0b2052bd ]
Add device type data for S32G2/S32G3 SoC.
FlexCAN module from S32G2/S32G3 is similar with i.MX SoCs, but interrupt management is different.
On S32G2/S32G3 SoC, there are separate interrupts for state change, bus errors, Mailboxes 0-7 and Mailboxes 8-127 respectively. In order to handle this FlexCAN hardware particularity, first reuse the 'FLEXCAN_QUIRK_NR_IRQ_3' quirk provided by mcf5441x's irq handling support. Secondly, use the newly introduced 'FLEXCAN_QUIRK_SECONDARY_MB_IRQ' quirk which handles the case where two separate mailbox ranges are controlled by independent hardware interrupt lines.
