Copy and paste error :-) Will fix in v3.

This is necessary for loading the coda driver as module.

In the imx_v6_v7_defconfig we changed the coda driver from built-in to module
in this commit:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch/arm/configs/imx_v6_v7_defconfig?h=v4.14-rc4&id=a5a56f07c2726cc801efccd23f8df29af04d6d19

This is necessary to avoid issues when the coda driver is probed prior
to the rootfs getting mounted.

Thanks
