Subject: [PATCH 2/3] drm/msm/dpu: Assign missing writeback log_mask

The WB debug log mask ended up never being assigned, leading to writes
to this block to never be logged even if the mask is enabled in
dpu_hw_util_log_mask via sysfs.

Fixes: 84a33d0fd921 ("drm/msm/dpu: add dpu_hw_wb abstraction for writeback blocks")
