1. Allocator api is determined by buffer type. 2. Allocator ctx is determined by both buffer type and buffer flags. 3. All allocator dma_heap / drm / ion / ext_dma should support different buffer flags. 4. The buffer flag supports cacheable / 32-bit / contig options. 5. Add flags update flow on allocator create process. 6. Add mpp_dmabuf_has_partial_ops to disable dmabuf partial ops when the kernel driver has bug.
