I've tested this series on sdm660 device, with userspace pd-mapper
service disabled, and don't see any regressions - e.g Wi-Fi/BT
still come online and work as before.
Debug logs:
https://paste.sr.ht/~minlexx/bd03db4c582a3275078ce4fd05ea76ce46a52b8e
Missing cdsp_root and adsp_sensors PDs are not currently an issue,
because those are not enabled yet on SDM660 or hard to test, so
