This fixes:
of_dma_request_slave_channel: dma-names property of node '/serial@fe660000' missing or empty
dw-apb-uart fe660000.serial: failed to request DMA
when I use ttyS2. Note this is only a warning, the UART still works. It
just doesn't use DMA.
Fixes: a3adc0b9071d ("arm64: dts: rockchip: add core dtsi for RK3568 SoC")
