drm/msm: add support to take dpu snapshot
Add the msm_disp_snapshot module which adds supports to dump dpu
registers and capture the drm atomic state which can be used in
case of error conditions.
changes in v5:
- start storing disp_state in msm_kms instead of dpu_kms
- get rid of MSM_DISP_SNAPSHOT_IN_* enum by simplifying the functions
- move snprintf inside the snapshot core by using varargs
- get rid of some stale code comments
- allow snapshot module for non-DPU targets
