Harshad Bhutada 950ab4c045 libgralloc-qsd8k: Dynamic ASHMEM
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.
