[PATCH] DMA interrupt mask value should not be hard coded

[PATCH] DMA interrupt mask value should not be hard coded

[chao bi]

In intel_mid_dma.c, when setup DMA controller, its interrupt
mask value is hard coded, it's not needed because this value
has already been initiated and set value according to DMA
channels which are used.
