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. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
