Subject: [PATCH v2 5/7] drm/msm/dsi: Use the new regulator bulk feature to specify the load

As of the patch ("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.

Signed-off-by: Douglas Anderson <dianders@...omium.org>

Changes in v2:
- ("Use the new regulator bulk feature to specify the load") new for v2.
