dmaengine: imx-sdma: Add support for version 3 firmware
Currently when version 3.1 of the mx6q SDMA firmware is used we get:
[ 0.392169] imx-sdma 20ec000.sdma: unknown firmware version
[ 0.399281] imx-sdma 20ec000.sdma: initialized
Add support for it.
Based on a patch from Shengjiu Wang from the internal FSL kernel.
