Add support for PIL loading of WPSS co-processor for SC7280 SOCs.
Changes from v4:
- Add yaml conversion for adsp/cdsp dt-bindings
- Change clock names in wpss dt-bindings

Add support for PIL loading of WPSS processor for SC7280
- WPSS boot will be requested by the wifi driver and hence
disable auto-boot for WPSS.
- Add a separate shutdown sequence handler for WPSS.
- Add multiple power-domain voting support
