If the imx-sdma driver is built as a module, the fsl-sai device doesn't
disable on probing failure, which causes the warning in the next probing:
==================================================================
fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable!
fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable!
fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable!
fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable!
fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable!
fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable!
==================================================================
Disabling the device properly fixes the issue.
