[Buildroot] [PATCH v3 6/8] board/freescale/common/imx8: Use post build generated uboot image if present

[Xavier Roumegue]

Stick the uboot image filename to "imx8-boot-sd.bin" in case the
final uboot image, embedding fw files, is generated thanks to a post
build script.

This takes precedence over all uboot images generating during uboot
build.

This should help to remove the dedicated imx8 config template file
