Add new algo for genalloc, it reserve a specific region of
memory matching the size requirement (no alignment constraint)
Signed-off-by: Zhao Qiang <qiang.zhao@freescale.com>
---
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_fixed_alloc
Changes for v11:
- rename gen_pool_fixed_fit to gen_pool_fixed_alloc

Changes for v9:
- splitted from patch 3/5, modify cpm muram management functions.
Changes for v10:
- modify cpm muram first, then move to qe_common
- modify commit.
Changes for v11:
- factor out the common alloc code
- modify min_alloc_order to zero for cpm_muram_alloc_fixed.

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"
