The drm/msm module bundles several drivers, each of them having a
separate OF match table, however only MDSS (subsystem), KMS devices and
GPU have corresponding MODULE_DEVICE_ID tables.

Add MODULE_DEVICE_ID to the display-related driver and to all other
drivers in this module, simplifying userspace job.

Fixes: 060530f1ea67 ("drm/msm: use componentised device support")

The Fixes tag points to the first commit introducing OF-based GPU
matching (and thus possibility for the headless GPU binding). Other
are not usable without the main MDP4 / MDP5 / DPU drivers, so they
didn't get the Fixes tags of their own.
---
Changes in v2:
- Rebased on msm/msm-fixes, dropping GPU chunk and updating the Fixes
  tag and the commit message.
- Link to v1: https://lore.kernel.org/r/20260219-msm-device-id-v1-1-9e7315a6fd20@oss.qualcomm.com

Applied to msm-next, thanks!
