mx8dx: Normalize MACHINEOVERRIDES implementation

The imx8dx-mek machine is similar to imx8qxp-mek and so the mx8qxp override
was included in the MACHINEOVERRIDES hierarchy. This is non-standard, and
the rework of the SOC overrides didn't handle it properly, leading to a
build break:

```

```

Fix the problem by removing mx8qxp from the mx8dx hierarchy and adapting
existing mx8qxp overrides appropriately.
