We need to use correct SOC name when naming the Kconfig.defconfig*
files.
So we need the following changes:
- mimx8mp -> mimx8ml8
- mimx8mm -> imx8mm6
- mimx8mn -> mimx8mn6
- mimx8mq -> mimx8mq6
Then we also need to take care of qualifiers name. Standard notation
uses "_" instead of "."
e.g : Kconfig.defconfig.mimx8mp.a53 -> Kconfig.defconfig.mimx8ml8_a53
