[PATCH] ARM: socfpga: fix uart DMA binding error

[Steffen Trumtrar]

socfpga.dtsi is missing the DMA channels for the uart nodes.
This will produce the following errors:

of_dma_request_slave_channel: dma-names property of node '/soc/***@ffc02000' missing or empty
ttyS0 - failed to request DMA

Provide the correct DMA channels to fix this.
