This patch add regulator_set_load() before enable regulator at
eDP phy driver.

Changes in v3:
-- no regulator_set_load before disable regulator
-- no supply name string change at probe
-- split into two patches

Should subject be "phy: qcom:" prefix?

These don't go here because this isn't a drm patch.

What does the comment mean? This is the load for 1.2V supply? Can we
have that sort of comment instead of "1.2 V"?
