ARM: dts: renesas: r9a06g032: Fix UART dma channel order

    arch/arm/boot/dts/renesas/r9a06g032-rzn1d400-db.dtb: serial@50000000: dma-names:0: 'tx' was expected
	    from schema $id: http://devicetree.org/schemas/serial/snps-dw-apb-uart.yaml#
    arch/arm/boot/dts/renesas/r9a06g032-rzn1d400-db.dtb: serial@50000000: dma-names:1: 'rx' was expected

    ...

The DT bindings specify a fixed order of the channels in the dmas and
dma-names properties, while the Linux driver does not care.
Get rid of the warnings by changing the order in the DTS to match the
bindings.
