ARM: dts: at91: Enable DMA on sama5d4_xplained console
commit ef8d02d4a2c36f7a93e74c95a9c419353b310117 upstream.
Enable DMA on usart3 to get a more reliable console. This is especially
useful for automation and kernelci were a kernel with PROVE_LOCKING enabled
is quite susceptible to character loss, resulting in tests failure.
