arm64: dts: rockchip: support CAN1-CAN2-UART4 adapter for RK3588 Jaguar
RK3588 Jaguar has a proprietary Mezzanine connector which exposes among
other things CAN1 and CAN2 controllers as well as UART4.
Add support for the CAN1-CAN2-UART4 Mezzanine adapter for RK3588 Jaguar
which exposes two CAN busses (CAN1 and CAN2) and an RS-232 UART, limited
to 250Kbps.
