cnss2: Update AOP Mbox interface for PDC config

Browse Source 
AOP Mbox interface message is updated to include the PDC name as WLAN
devices like KIWI needs 2 PDCs.

Also following updates are done:
1. Always open Mbox channel for OL CPR update.
2. Add device tree config for PDC - VReg mapping and
   WLAN device PDC Init table.
3. Reconfig PDC based on WLAN device connected to the platform.
4. Add debug interface for PDC update.
