msm: ion: Allow non contiguous allocations in secure heap.
The cma secure heap allocates contiguous memory. This causes
the memory to be fragmented if several allocation and free
requests are made with buffers of various sizes. Introduce
the new ion flag(ION_FLAG_ALLOW_NON_CONTIG), which can be
passed to indicate a scatter gather list of smaller non
contiguous buffers can be allocated instead of a single
giant chunk.
