Santosh Shilimkar 52176e7083 ARM: OMAP: Dispatch only relevant DMA interrupts 
This fixes the spurious interrupt issue on a DMA channel.

In OMAP sDMA, contrast to the SDMA.DMA4_CSRi registers, the
SDMA.DMA4_IRQSTATUS_Lj registers are updated regardless of
the corresponding bits in the SDMA.DMA4_IRQENABLE_Lj registers.
Since there are four sDMA interrupt lines and if more than one
line is actively used by two concurrently running sDMA softwares
modules,then the spurious interrupt can be observed on the other
lines.

Fix in this patch will only dispatch the relevant and enabled
interrupts on a particular line thus perevting spurious IRQ.
