msm: camera: csiphy: Update logic for lane enablement

Browse Source 
Currently lane enablement is happening as a part of lanemask
field, which is send by UMD. Lane enablement should be purely
depends on laneCnt and laneAssign attributes. Also, combo mode
sensors needs to come with combo mode flag set from the UMD.
This change updates the logic for lane enablement with respect
to laneAssign and laneCnt, and also covers all combomode selection
as per the request. This change also enables the sensors to acquire
and streamon/streamoff at anytime in session.
