Sebastian Andrzej Siewior 830acf9e30 tty: serial: 8250_omap: do not use RX DMA if pause is not supported 
The 8250-omap driver requires the DMA-engine driver to support the pause
command in order to properly turn off programmed RX transfer before the
driver stars manually reading from the FIFO.
The lacking support of the requirement has been discovered recently. In
order to stay safe here we disable RX-DMA completly on probe.
The rx_dma_broken assignment on probe could be removed once we working
pause function in omap-dma.
