Implement the MHI controller configuration for QCN9575.

Add ath12k_wifi8_mhi_config_qcn9575 with IPCR channels 20 and 21 and
control and data event rings in wifi8/mhi.c, and export it through
wifi8/mhi.h. Update the QCN9575 hw params entry to use
ath12k_wifi8_mhi_config_qcn9575. Build wifi8/mhi.c from wifi8/Makefile.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.6-01243-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c7-00108-QCAHMTSWPL_V1.0_V2.0_SILICONZ_UPSTREAM-3
