k3-am642-tqma64xxl.dtsi should be fixed, it slipped past me and
shouldn't be used as a reference.

The bootloader might not fill it out at all, what if we start
using the new MTD GPT partitions? Then the new bootloaders
will have to start *removing* these stale half-nodes.

If the bootloader is going to add fixed partitions it should do
the whole job. There is no good reason to have a half complete
nodes here.
