Precedence: bulk

Doing a for loop in every DPU HW block driver init to find a catalog
entry matching the given ID is rather useless if the init function
called by RM already has that catalog entry pointer, and uses exactly
its ID to drive this init and for loop.  Remove all that machinery to
drop quite some lines of unnecessarily-complicated code, and the
fallibility that comes with it, by simply giving _init() the catalog
entry pointers straight away.

Also clean up some unused struct members, and assign a log_mask for WB.

---
Changes in v2:
- Replace "sysfs" with "debugfs" in patch 2/3 description;
- Reorder WB log_mask fix as patch 1;
- Drop Fixes: tags from "unused struct members removal";
- Replace dpu_mdss_cfg parameter in dpu_hw_sspp_init() with immediate
  dpu_ubwc_cfg pointer;
- Replace dpu_mdss_cfg parameter in dpu_hw_ctl_init() with immediate
  dpu_lm_cfg array pointer.

Marijn Suijten (3):
      drm/msm/dpu: Assign missing writeback log_mask
      drm/msm/dpu: Drop unused members from HW structs
      drm/msm/dpu: Pass catalog pointers directly from RM instead of IDs
