[Buildroot] [PATCH v2 1/4] board/zynqmp/post-build.sh: auto-generate extlinux.conf

[Frager, Neal]

Hi,

> This patch uses the BR2_ROOTFS_POST_SCRIPT_ARGS to auto-generate the extlinux.conf file, so developers will only need to modify the board_defconfig file to change the console and boot file system locations.
