machine:mx8m:dt: Fixed the devicetrees for mx8mm/mx8mp

In Yocto Kirkstone, we use the 5.15.5 kernel from NXP for the i.MX8
devices. In the kernel repository we moved all G&F and K&K devicetrees
to a new folder called seconorth.
Edit the machine configurations to reflect this change and build the
correct devicetrees.
