MLK-14498-5 tty: serial: imx: fix the DMA issue The commmunity driver uart DMA don't work, it better to use 4.1.y DMA process mechanism, so there have many conflict during code merging. Decisively, to use 4.1.y commit f00cf8855eaa in the merge point for DMA implemention. In DMA mode, don't involve CPU interrupt, remove .imx_dma_rxint() function. After the patch, DMA and CPU mode both work fine with the current SDMA driver. Signed-off-by: Fugang Duan <fugang.duan@nxp.com>
