[Buildroot] [git commit] board/freescale/common/imx: make imx8-bootloader-prepare more generic

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=a534676dc334879f69a9834aaf47ed440e80a381
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Allow user to override the hardcoded dtb name by using
BR2_ROOTFS_POST_SCRIPT_ARGS.

The only user of this script, configs/freescale_imx8mqevk, is updated
accordingly.
