minigbm: refactor and rename mapping struct
Since some drivers (AMDGPU, Tegra) may have to do expensive tiling
and detiling operations, we should try to take advantage of the
access regions passed in by gralloc and gbm. Let's refactor struct
map_data so we can separate the actual mapping and access region.
Here is the Coccinelle rule used in this change:
@@ struct map_info *M; @@
- (M)
+ M->vma
In addition, struct map_data was also renamed to struct mapping.
