data: Use auto-generated but hardcoded autosuspend hwdb file

This solves various problems:
 1. It stays the same also if some drivers have been disabled
 2. It uses a stable path for being imported by systemd
 3. It is still checked for its validity by tests
 4. It can be auto-generated using a simple command
