riscv: dts: allwinner: d1: Add CAN controller nodes
The Allwinner D1, T113 provide two CAN controllers that are variants of the R40 controller. I have tested support for these controllers on two boards: - A Lichee Panel RV 86 Panel running a D1 chip - A Mango Pi MQ Dual running a T113-s3 chip Both of these fully support both CAN controllers.
