Add Sony PlayStation controller entries to 70-sound-card.hwdb so that their
ALSA sound devices are tagged with SOUND_FORM_FACTOR=controller:
- DualSense (054c:0ce6)
- DualSense Edge (054c:0df2)
- DualShock 4 CUH-ZCT1x (054c:05c4)
- DualShock 4 CUH-ZCT2x (054c:09cc)
These controllers expose USB audio but are neither headsets nor speakers.
Pinning them in the hwdb ensures they are identified correctly before any
fallback matching occurs.
