Variants of minigbm_create_default_device are open-coded in multiple places. This should be used wherever minigbm can be assumed. BUG=none TEST=manual check that the function works Change-Id: I3ad9897355ab72080fdca329674df09087b9adfd Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/minigbm/+/4163418 Reviewed-by: Yiwei Zhang <zzyiwei@chromium.org> Tested-by: Chia-I Wu <olv@google.com> Commit-Queue: Chia-I Wu <olv@google.com>
