With the current implementation of wmi init command, there is no provision for the host driver to provide mem chunks addresses with more than 32-bit, to the firmware. WCN3990 is a 35-bit target and can accept mem chunks addresses which are above 32-bit.
If firmware supports address range more than 32 bit, it advertises the support by setting the WMI_SERVICE_EXTEND_ADDRESS service. Based on this service fill the upper bits of paddr while providing the mem chunks in the wmi init command.
