Currently driver marks cache type as static when it sends valid
channel list to firmware to use for roaming. When cache type is
static, driver will not add WMI_ROAM_SCAN_MODE_RSSI_CHANGE in
wma_process_roaming_config.
Roam scan may not trigger upon RSSI change when mode does not
have WMI_ROAM_SCAN_MODE_RSSI_CHANGE and may have issues related
to roaming.
Mark channel list as dynamic based on newly added ini
"force_rssi_trigger" for valid channel list as well.
With this new ini , customers can tune the behaviour of
roaming scan in firmware based on RSSI trigger or periodic.
