[Thomas:
 - use SDPX license codes
 - add entry to DEVELOPERS file
 - drop BR2_PACKAGE_QT5BASE_LICENSE_APPROVED logic, since we removed this option
 - select BR2_PACKAGE_QT5DECLARATIVE and
   BR2_PACKAGE_QT5DECLARATIVE_QUICK instead of using a "depends on"
   and propagate the appropriate dependencies]
