On systems where KERNEL_IMAGETYPE is not set to fitImage, one needs to either pass an DTB or a path to a directory where DTBs are located on the rootfs. When FDT property in extlinux is provided, FDTDIR isn't used (and actually u-boot-extlinux-config doesn't even write it to the configuration file). When relative paths are used, they are relative to the directory where extlinux.conf is stored[1]. Since the DTBs are stored in /boot, just providing the filename of the DTB won't work because extlinux in U-Boot will search for it in /boot/extlinux. We should therefore either use ../ prefix for relative paths or use /boot to make it absolute. /boot is more explicit and easily parseable, so let's use the latter.
