disp: msm: set voltage to min before disable

Browse Source 
This change sets the regulator voltage to zero for all
those regulators which support voltage scaling before
disabling the regulator. Failing to do so causes the regulator
vote to set to the last min value specified in the previous
set voltage call.
Additionally modified the config regulator api and renamed to
get regulator because of the above change.
