dmaengine: imx-dma: dont complete descriptor for cyclic dma
the cookie updates completed the cyclic dma descriptor wrongly. This caused the

dmaengine: i.MX: Add support for interleaved transfers.
i.MX2 and i.MX1 chips have the possibility to do
interleaved transfers with two constraints:
- Only one chunk can be used (i.e. only 2D transfers are allowed).
- Only 2 interleaved configurations can be applied at the same time
for all channels.
Since this patch adds a new resource 'slots_2d' which is shared
by all the DMA channels and to avoid disgustin locking BUGs, the
'lock' member has been moved to the global 'imxdma_engine' structure.

dmaengine: ensure all DMA engine drivers initialize their cookies
Ensure all DMA engine drivers initialize their cookies in the same way,
so that they all behave in a similar fashion. This means their first
issued cookie will be 2 rather than 1, and will increment to INT_MAX
before returning 1 and starting over.
In connection with this, Dan Williams said:

dma: imx-dma: fix signedness bug
mxdmac->channel was unsigned, so check (imxdmac->channel < 0) for
failed imx_dma_request_by_prio() made no sence. Explicitly check
signed values.
Also, fix uninitialzed use of ret.

dmaengine: Add Freescale i.MX1/21/27 DMA driver
This driver is currently implemented as a user to the old i.MX
DMA API. This allows us to convert each user of the old API to
the dmaengine API one by one. Once this is done the old DMA
driver can be merged into the i.MX dmaengine driver.
V2: remove some debug leftovers and unused variables
