wic: add new wks file to use boot container for mx8m

Add new WKS template file, which uses the boot container provided by
mainline U-Boot.

Boot container built as a part of U-Boot packs binary components into
two separate files, namely 'flash.bin' and 'u-boot.itb'. First file
contains SPL, while second one represents the FIT image containing
U-Boot and ATF blob.

+# short-description: Create SD card image with a boot partition for i.MX8M
+# long-description:
+# Create an image that can be written onto a SD card using dd for use
+# with i.MX8M SoC family
+# It uses binary boot container called flash.bin provided directly by
+# the U-Boot recipe, and U-Boot ITB files which is created by binman utility
+# of U-Boot.
+# Those files are added it into the boot partition, which is populated as a
+# raw copy into the image.
+# Boot container prepared by U-Boot already container SPL, U-Boot itself,
+# U-Boot DTB file, ATF, and optional OP-TEE components.
+#
+# The disk layout used is:
+#  - ----------- -------------- ----------------------------
+# | | flash.bin | u-boot.itb |     boot     |    rootfs    |
