Initial support for interleaved transfer with sDMA.
The implementation only supports DMA_MEM_TO_MEM and frame_size must be 1.
sDMA needs to be configured for double indexing when ICG is needed.

Implement the function which wait until a dma channel is stopped to have
a synchronization point.
This also protects the pxad_remove() from races, such as spurious
interrupts while removing the driver, because :
- as long as there is one dma channel requested, ie. dma_chan_get() but
no dma_chan_put(), the try_module_get() of dma_chan_get() prevents
the remove() routine from running
- when the last channel is released, ie. the last dma_chan_put() is
called, if there is a running DMA, pxad_synchronize() is called
- pxad_synchronize() waits for the channel to stop, which in turn
ensures on pxa architecture that the interrupt cannot be fired anymore
