I have narrowed this down to the new PiSP driver upstreamed in libcamera. They are matching the wrong entity names for CFE devices.

Curiously, Raspberry Pi's fork of libcamera still uses the old match strings, even when they upstreamed these changes to Debian: https://github.com/raspberrypi/libcamera/blob/d83ff0a4ae4503bc56b7ed48cd142c3dd423ad3b/src/libcamera/pipeline/rpi/pisp/pisp.cpp#L883

This might suggest that there may be changes to the camera related devicetree overlays in the future. For now the fix will be to try for both older and newer match strings
