wifi: ath12k: configure RDDM size to MHI for device recovery
RDDM is Ram Dump Debug Module which is used to debug issues when the
firmware encounters an error. The rddm_size is needed by the firmware
while MHI goes to the RDDM state. Provide the size to MHI subsystem so
that the firmware restart works when the firmware crashes.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
