dma: imx-sdma: use chn_real_count to report residue for UART
dma: imx-sdma
So move updating of BD back to tasklet.

ssful, but as BD_RROR flag is set, client side
will still think the transfer failed.
This patch clears BD_RROR flag before pass it to sdma script.

Previously when channel0 timeouts to finish its task,
sdma_run_channel0() just returns without disable channel0,
this will cause continuous interrupt later when channel0
finishs its task and set channel0 interrupt bit.

nnel0 timeouts, it won't cause irq storm,
also adds lock to prevent irq routine to clear this bit when
sdma_run_channel0() is busy checking it.
