PNP_GetDeviceList and PNP_GetDeviceListSize:
- Do not return CR_CALL_NOT_IMPLEMENTED by default.
- pulLength is counted in characters, not in bytes!
- Use the correct Relations value for PowerRelations.

[NDK]
Add the PowerRelations value to a comment.

[DEVMGR]
CM_Get_Device_ID_List_Size_ExW and CM_Get_Device_ID_List_ExW count the buffer length in characters, not in bytes!
