arm64: dts: imx8mm-kontron: Remove low DDRC operating point

For some reason there is a problem with finding a DDR configuration
that works on all operating points and all LPDDR4 types used on the
SoM. Therefore the bootloader currently doesn't configure the lowest
of the three operating points. Let's also skip this in the kernel
devicetree to make sure it isn't used.
