msm: mdss: use regulator get optional API for optional reg

Browse source 
"vdd-cx" is optional regulator and usage of incorrect API
returns the dummy regulator. Display driver tries to
enable/disable this regulator on each suspend/resume and
prints error based on return value. This change uses
correct API for optional regulator to avoid unnecessary
error messages on each suspend/resume.
