u-boot: Add support to use uboot-extlinux-config class

Use uboot-extlinux-config class to create extlinux.conf file and then
install inside /boot/extlinux directory and also put file to deploy
dir. This file will be only create if UBOOT_EXTLINUX is set to 1.

You can use DEPLOYDIR/extlinux.conf file to install into final image
using wic setting:

IMAGE_BOOT_FILES_append = " extlinux.conf;extlinux/extlinux.conf"
