weston:rotation: fix output name for seco-mx6*-fsl
A framebuffer is used instead of DRM on i.MX6 boards with NXP based kernel. The output name in weston.ini is "fbdev".
Dear all, On Thursday, 4th September 2025, we will test the new disaster recovery environment. A disaster recovery test will take place between 4:00 PM and 6:00 PM CEST. Please refrain from making any changes, as they will be lost. Once testing is complete, the production environment will be restored. Thank you for your understanding.
