Justin Philip d616660fe6 libhwcomposer: libgralloc Set MDP_SMP_FORCE_ALLOC flag 
For PROTECTED but NON SECURE layers set MDP_SMP_FORCE_ALLOC flag
to allow SMP allocation and prevent GPU fallback
In Such cases if video resolution changes dynamically
it fails to display layer due to GPU fallback.
Use this flag for FB layer composition and depricate
MDP_BACKEND_COMPOSITION flag.
