RDDM is RAM DUMP DEBUG module, it is used to debug issues when firmware
encounters an error.
The rddm_size is needed by firmware while MHI enter RDDM state. Add it
to support device recovery when ath12k receive MHI_CB_EE_RDDM message.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
