rk3576 can is a new controller:
Support CAN and CANFD protocol.
Support DMA

There are major differences from the previous rk3568. All errata on the
rk3568 have been fixed and redesigned.

I'm not convinced that we need a second driver for the hardware that has
the erratas fixed. The mainline driver has quirks that allow you to
specify if the IP core needs workarounds for the errata or not.
