Add support for i.MX95-based boards. The boot container build process
differs a bit from i.MX93, thus the addition of a new script. Most
notably, there's at least 2 new images to be included (i.e. SM and
DDR/TCM OEI).

+# by imx-mkimage by running:
+#
+#  make SOC=iMX95 OEI=YES LPDDR_TYPE=lpddr4x flash_a55
+#
+# As such, please be mindful of the fact that this script may not work

+# TODO: improve this script such that it can handle multiple targets
