The revert commit 36a6418bb1259 ("Revert "ARM: dts: stm32: add CAN support on stm32f746"") prevented parsing errors due to the lack of CAN3 binding. Now that the binding definition for CAN3 is available in the mainline thanks to commit 8f3ef556f8e1a ("dt-bindings: mfd: stm32f7: Add binding definition for CAN3"), we can re-add the CAN support and make the driver usable again.
