weston.init: import from meta-arago

- Move the am62xx specific files into their own directory so
  that they do not clash with files of the same name used by other
  architectures.
- Additionally explicitely set the weston backend to drm.
- Additionally set the idle timeout to 0 in weston.ini, i.e. disable
  that functionality.
- Start weston through a systemd service.
