I have thought about that.. however, the only configuration, where we do not 
need the BLOCK_IRQ is in audio, and only when we are running in 'no period 
wakeup' mode.
In all other cases we need to have the BLOCK_IRQ enabled.
I have looked at the other OMAP drivers, which uses the DMA and all assumes, 
that the BLOCK_IRQ is enabled out of box.

We can modify all OMAP drivers, and the dma core, or we can just disable the 
BLOCK_IRQ at the only case, when it is not needed.
