When the firmware doesn't advertise the
wmi_service_hw_db2dbm_support target capability host should send
rssi values in SNR equivalent so that the hardware can trigger
interrupts. Else low rssi, idle roam, emergency deauth roam
interrupts will not be triggered.
Add changes to convert RSSI values coming from ini to
SNR and send it to firmware. Below ini parameters need
conversion:
bss_load_trigger_2g_rssi_threshold
bss_load_trigger_5g_rssi_threshold
idle_roam_min_rssi
candidate_min_rssi_for_beacon_miss
candidate_min_rssi_for_disconnect
