Currently in combo mode csiphy preamable enable is determined with
premalbe flag set previously and current sensor configuration setting.
In case of non combo mode usecase if config packet is coming back to
back current condition check misinterpret it as combo mode and fails
with incorrect operation. This change adds the combo_mode condition
check along with other to correctly detemine combo mode and non combo
mode usecase and behaves accordingly.
