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

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.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
