ARM: dts: sun6i: a31: Switch dma-names order for snps,dw-apb-uart nodes

Browse Source 
Commit 370f696e44 ("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.
