sdm: Fix topology after adding new mode

1. Driver does not populate topology information for the new
   resolution mode being added for virtual display. So hardcode the
   topology information in user space based on the width
2. Do not initialize the default mode list for connector, as user
   space adds the mode to the mode list as and when requested.
