Sascha Hauer 8267f16e8b 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.

Sascha Hauer 1f1846c6ce 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
