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.
