From: Cunhao Lu <[email protected]> RK3588 integrates a Rockchip CAN-FD controller variant that is not fully compatible with RK3568v2. The RX FIFO count register field is encoded in bits 7:5 on RK3588, while RK3568v2 uses bits 6:4. Add a dedicated rockchip,rk3588-canfd compatible to describe this variant. Do not use rockchip,rk3568v2-canfd as a fallback, because that would describe a register layout that does not match the hardware.
