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.
