riscv: dts: allwinner: d1: Switch dma-names order for snps,dw-apb-uart nodes
Commit 370f696e4474 ("dt-bindings: serial: snps-dw-apb-uart: add dma & dma-names properties") documented dma-names property to handle Allwinner D1 dtbs_check warnings, but relies on the rx->tx ordering, which is the reverse of what a bunch of different boards expect. The initial proposed solution was to allow a flexible dma-names order in the binding, due to potential ABI breakage concerns after fixing the DTS files. But luckily the Allwinner boards are not affected, since they are using a shared DMA channel for rx and tx. Hence, the first step in fixing the inconsistency was to change dma-names order in the binding to tx->rx. Do the same for the snps,dw-apb-uart nodes in the DTS file.
