drm: Add and export function drm_fb_cma_sync_non_coherent
This function can be used by drivers that use damage clips and have
CMA GEM objects backed by non-coherent memory. Calling this function
in a plane's .atomic_update ensures that all the data in the backing
memory have been written to RAM.
v3: - Only sync data if using GEM objects backed by non-coherent memory.
- Use a drm_device pointer instead of device pointer in prototype
v5: - Rename to drm_fb_cma_sync_non_coherent
- Invert loops for better cache locality
- Only sync BOs that have the non-coherent flag
- Move to drm_fb_cma_helper.c to avoid circular dependency
