board/freescale: add i.MX95 support

Browse Source 
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).

[Julien:
 - add "set -eu" in script
 - rename "imx9-boot-sd.bin" to "flash.bin" after commit aa1ed6e741
 - remove "TODO:"

# VERY IMPORTANT: a lot of this code here is hardcoded such that
# it's able to generate a flash.bin equivalent to the one generated
# 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
# if you wish to change the make target or one of its parameters.
