drm_hwcomposer: libdrm gralloc_handle: modifiers and YUV support 1. Import DRM modifier field from libdrm's gralloc_habdle. 2. Recently lock_ycrcb() was added to gbm_gralloc() [1], mesa3d uses this function to obtain CrCb plane data (offsets, strides). Use the same alhorythm in drm_hwcomposer. This allows GPU offloading during video playback. (Tested using Gallery app and SkyTube).
