[sbabic at denx.de]

> After commit 395110284b56 ("nitrogen6x: Populate FDTFILE at build-time
> for all platforms") iMX.6Q Sabrelite fails to boot due to a bad fdtfile
> string:
>   Retrieving file: /dtbs/5.18.0-0.deb11.4-armmp/"imx6q-sabrelite".dtb
>   ** File not found /dtbs/5.18.0-0.deb11.4-armmp/"imx6q-sabrelite".dtb **
> CONFIG_DEFAULT_DEVICE_TREE option is string typed, so __stringify() is
> adding extra quotes. Remove this.
