drm: panel: Enable prepare_prev_first flag for samsung-s6e panels
Enable the drm panel prepare_prev_first flag so-that the previous
controller should be prepared first before the prepare for the
panel is called.
samsung-s6e3ha2, samsung-s6e63j0x03 and samsung-s6e8aa0 are the
effected samsung-s6e panels for this change.
This makes sure that the previous controller, likely to be a DSI
host controller should be initialized to LP-11 before the panel
is powered up.
