ath11k: Change qcn9074 fw to operate in mode-2

In mode-2 QCN9074 firmware uses 15MB of host memory and firmware
request 1MB size segements in QMI, whereas in mode-0 firmware
uses 45MB of host memory and each segment is of 2MB size.
In mode-2 firmware operates with reduced number of vdevs and peers.

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1-01838-QCAHKSWPL_SILICONZ-1
