When USE_ASHMEM is set, ASHMEM will be used only for non-MDP composition.
This implementation will force to use PMEM for MDP composition case. This
will allow using ASHMEM or PMEM at run time, depending on the composition
type. USE_ASHMEM would mean that use ASHMEM where possible.
This will also make sure that video works properly when dynamic ASHMEM
feature is enabled on 7x27 / 7x27a / 7x25a targets.

libgralloc-qsd8k: Add support for non-aligned width on HDMI
While creating overlay channel for HDMI consider the aligned
width and set the crop rectangle to the actual width and height.

The purpose of this change is to add support for allocating gralloc buffers
from either /dev/pmem or /dev/pmem_adsp depending on the usage flags. It does
this by factoring out and abstracting the interactions with the pmem device.
For /dev/pmem allocations, the kernel allocator is not used, so a single master
fd is opened, and all the allocations are sub-allocated from that by gralloc.
For /dev/pmem_adsp the kernel allocator is used, so it simply opens a new fd
for each allocation.
A very basic unit test that can be run on the host is included. It requires
gtest, so to run it on a host system gtest must (currently) be compiled with
BUILD_WITH_ASTL=true.
