[PATCH V2] dma: mmp_tdma: disable irq when disabling dma channel

[Qiao Zhou <zhouqiao@marvell.com>]

V2 -> V1:
1, mask dma interrupt when disable DMA channel.
2, remove patch v1.

if the dma channel is disabled without interrupt masked, the interrupt
status may still be set. next time when dma channel is enabled again,
the old interrupt status may trigger the interrupt wrongly. we need to
mask the interrupt when dma channel is disabled.
