ASoC: fsl: imx-ssi: fix probe on imx31
On imx31 with mc13783 codec the FIQ is not necessary and not enabled as DMA transfer is available. Change the probe() function to fail only if both FIQ and DMA are not available. Signed-off-by: Philippe Rétornaz <philippe.retornaz@epfl.ch> Signed-off-by: Mark Brown <broonie@linaro.org>
