arm64: dts: rockchip: Fix UART DMA support for RK3528
Trying to use UART2 DMA for Bluetooth on ArmSoM Sige1 result in tx
timeout when using dma-names = "tx", "rx" as required by the dt-binding:
Bluetooth: hci0: command 0x0c03 tx timeout
Bluetooth: hci0: BCM: Reset failed (-110)
Change the dmas order to fix UART DMA support on RK3528.
With this fixed Bluetooth can be loaded using DMA on ArmSoM Sige1:
Bluetooth: hci0: BCM: chip id 159
Bluetooth: hci0: BCM: features 0x0f
Bluetooth: hci0: BCM4362A2
Bluetooth: hci0: BCM4362A2 (000.017.017) build 0000
Bluetooth: hci0: BCM4362A2 'brcm/BCM4362A2.hcd' Patch
Bluetooth: hci0: BCM: features 0x0f
Bluetooth: hci0: BCM43752A2 UART 37.4MHz Ampak AP6398 sLNA iLNA CL1 [Version: 1091.1173]
Bluetooth: hci0: BCM4362A2 (000.017.017) build 1173
