"soc<cpu>@<addr>" is no longer recommended.

- Drop device_type property
- add: compatible = "fsl,mpc5121-immr";

Specify the *exact* version in compatible first. You can add generic
forms after that if you like, but the first entry should always be
exact (as per the generic names recommended practice). It should be:
compatible = "fsl,mpc5121-psc-uart".
Also, make sure all compatible properties have the 'fsl,' prefix.

Drop port-number. Aliases will be used instead.
