[PATCH] arm64: dts: rockchip: rk3399: Hook up DMA for UARTs

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens at csie.org>

The RK3399 has two DMA controllers, one of which is wired up to work
with the SPI controllers and UARTs. The SPI controllers are already
hooked up, but the UARTs aren't.

Add the "dmas" and "dma-names" to the UART device nodes to hook up DMA.
