Hi Marcel,

This avoids firmware load error and sysfs fallback reported as follows:

[    0.199448] imx-sdma 302c0000.dma-controller: Direct firmware load
 for imx/sdma/sdma-imx7d.bin failed with error -2
[    0.199487] imx-sdma 302c0000.dma-controller: Falling back to sysfs
 fallback for: imx/sdma/sdma-imx7d.bin
unfortunately this isn't an explanation why this solve the issue. It
looks like that the SDMA firmware is not available for the kernel. Build
the driver as a module hide the issue and just load it if the rootfs is
available.

What makes you sure that the driver is not critical for other boards
during boot?
