[POWERPC] QE: get rid of most device_types and model

Browse Source 
Now we're searching for "fsl,qe", "fsl,qe-muram", "fsl,qe-muram-data"
and "fsl,qe-ic".

Unfortunately it's still impossible to remove device_type = "qe"
from the existing device trees because older u-boots are looking for it.

i) Root QE device
Required properties:
- device_type : should be "qe";
- compatible : should be "fsl,qe";
- model : precise model of the QE, Can be "QE", "CPM", or "CPM2"
- reg : offset and length of the device registers.
- bus-frequency : the clock frequency for QUICC Engine.
