msm: mdss: configure SMART_PANEL_ALIGN_MODE for split display



As per HW recommendation, configure the SMART_PANEL_ALIGN_MODE
control to start of frame for command mode split display use
cases. This will avoid any issues related to the skew that can
develop between the 2 interfaces used for sending data to panel.
