We use the terms "flags" and "usage" interchangeably in this repo,
since they essentally mean the same thing. However, let's be a
little more consistent since it's kind of confusing, especially
when buffer map flags come to play. Let's:
- refer to everything in the drv_* layer as use_flags
- refer to everything in the gbm/gralloc layers as
usages
