[v4,4/6] drm/msm/dsi: Use the new regulator bulk feature to specify the load

Commit Message

Doug Anderson Aug. 4, 2022, 2:38 p.m. UTC

As of commit 6eabfc018e8d ("regulator: core: Allow specifying an
initial load w/ the bulk API") we can now specify the initial load in
the bulk data rather than having to manually call regulator_set_load()
on each regulator. Let's use it.
