QE/CPM: move muram management functions to qe_common

Browse source 
QE and CPM have the same muram, they use the same management
functions. Now QE support both ARM and PowerPC, it is necessary
to move QE to "driver/soc", so move the muram management functions
from cpm_common to qe_common for preparing to move QE code to "driver/soc"
