powerpc/QE: switch to the cpm_muram implementation
This is very trivial patch. We're transitioning to the cpm_muram_*
calls. That's it.
Less trivial changes:
- BD_SC_* defines were defined in the cpm.h and qe.h, so to avoid redefines
we remove BD_SC from the qe.h and use cpm.h along with cpm_muram_*
prototypes;
- qe_muram_dump was unused and thus removed;
- added some code to the cpm_common.c to support legacy QE bindings
(data-only node name).
- For convenience, define qe_* calls to cpm_*. So drivers need not to be
changed.
