arm64: dts: tqma8mpql-mba8mpxl-lvds: Rename overlay to include display name

This platform supports several displays, so rename the overlay to reflect
the actual display being used. This also aligns the name to the other
TQMa8M* modules. Apply the same change for MBa8MP-RAS314 as well, as it
uses the same overlay.
