wifi: ath12k: add support to allocate MLO global memory region

Browse source 
To enable Multi-Link Operation (MLO), QCN9274 firmware requests MLO global
memory (MLO_GLOBAL_MEM_REGION_TYPE). This memory region is shared across all
the firmware (SoC) that are participation in the MLO.

Hence, add support to allocate and free MLO global memory region.  Allocate one
MLO global memory per struct ath12k_hw_group and assign the same memory to all
firmware in the same struct ath12k_hw_group. WCN7850 firmware does not request
this memory type, therefore this change will have no impact on WCN7850 device.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00210-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
