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"

Use genalloc to manage CPM/QE muram instead of rheap.

Changes for v9:
- splitted from patch 3/5, modify cpm muram management functions.
Changes for v10:

Add new algo for genalloc, it reserve a specific region of

Changes for v9:
- reserve a specific region, if the return region
- is not during the specific region, return fail.
Changes for v10:
- rename gen_pool_fixed_fit to gen_pool_fixe
Bytes alignment is required to manage some special RAM,
so add gen_pool_first_fit_align to genalloc,
meanwhile add gen_pool_alloc_algo to pass algo in case user
layer using more than one algo, and pass data to
gen_pool_first_fit_align(modify gen_pool_alloc as a wrapper)

Hello,
I have found a possible out of bounds reading in

after the for iteration. What happens is that in the last iteration
the i index is incremented to 16, checked (i
