MLK-12256: firmware: imx: sdma: fix bugs in uart script code
Fix two below bugs in script:
-- check error flag in FIFO data, thus dma will stop once the error happen
when real HW error triggered by switch boundrate, overun,etc. Actrually,
no need to check in script since UART driver will handle this.
-- clear other status bit in USR1.
