wifi: ath12k: add helper function to init partner cmem configuration

Browse Source 
In the Inter Multi-Link Operation, the primary device is expected to receive
the partner device buffer. Therefore, each device initializes the partner
device buffer in their cmem configuration. So add a helper function to
initialize the partner device buffer in their cmem configuration.
