Marek Szyprowski 6ffaa6e0f3 serial: samsung: fix maxburst parameter for DMA transactions ...

commit aa2f80e752 upstream.

The best granularity of residue that DMA engine can report is in the BURST
units, so the serial driver must use MAXBURST = 1 and DMA_SLAVE_BUSWIDTH_1_BYTE
if it relies on exact number of bytes transferred by DMA engine.
