qcom: smb2: disable h/w autonomous parallel control

Browse source 
The charger driver ensures that parallel charging remains
disabled as long as AICL is below threshole (1400mA) using
it's software voting mechanism(USBIN_I_VOTER), thus disable
hardware's autonomous control of input current based parallel
charging.
