Bartlomiej, could you please test the patches on Samsung Exynos4412?

The patch "dmaengine: pl330: make cyclic transfer free runnable" fixes
sound click problem. So if you noticed sound clicks on your board,
please test the patches.

The patch "dmaengine: pl330: don't emit code for one iteration loop"
is simple improvement allows to save some bytes of pl330 MicroCode
buffer.

The patch "dmaengine: pl330: cleanup quirk pass code" is improvement
intended to hide struct pl330_dmac from low-level functions.
It partially revert changes introduced by 271e1b86e691 "dmaengine:
pl330: add quirk for broken no flushp".
