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.

It might have been better, if the previous patch had only removed the
load_setting on disable and inlined the dsi_host_regulator_disable().
Then this patch would drop the regulator_set_load() from
dsi_host_regulator_enable() path and inline it. Then it would have been
more obvious that after these two changes the time when we set loads is
not changed.

Changes in v3:
- Update commit message to point at the git hash of the regulator change.
Changes in v2:
- ("Use the new regulator bulk feature to specify the load") new for v2.
